If the menstruation is delayed for at least 1 day, the woman is already beginning to sound the alarm. The only question is whether the pregnancy has come or not. Always come to the aid of a pregnancy test. However, it is not always possible to interpret the result unequivocally. Such is the situation when there are monthly and weak second strip in the test.
The principle of the test
The test results are based on the reaction of the reagent to human chorionic gonadotropin in a woman’s urine. It appears from the moment of implantation of the egg into the uterus, with each passing day its rate is growing rapidly. In the morning, his urine contains much more. With each serving during the day, hCG weakens. In the evening, to do the test, in general, is impractical.
Each test has its own sensitivity. Therefore, it is recommended to buy 2 at once from different manufacturers. The test with high sensitivity in the presence of pregnancy will show 2 bright stripes. With less - the second weak. However, you should not rush to conclusions either. It is recommended to double-check in a few days.
Weak second strip on the dough - causes
In the absence of menstruation, a weak second strip in the test means pregnancy. But if the analysis is carried out on the second week of delay, there is a pathology in the hormonal background. An insufficient amount of progesterone makes the pregnancy not quite full. If a woman has a desire to save it - you should seek help from specialists. The situation is in question, when there is a weak second strip on the test, there are monthly.
Pregnancy with hormonal disorders - spontaneous rejection begins.
- Ectopic pregnancy - begins with daubs, goes into a heavy bleeding.
- An individual feature of the body - in some women, the first 3 months of pregnancy are menstruating. But the duration is less than usual, the allocation is scarce.
- Maturation 2 eggs. The situation is rare, but there is a place to be. Then one egg cell is fertilized, the second continues to prepare for menstruation.
- Poor quality test. It is necessary to pay attention to the sensitivity of the manufacturer. Cheap tests often give false or dubious results.
- Non-compliance with the rules of the analysis. A weak second gray bar indicates that the reaction did not occur. This is due to too long keeping the reagent in the urine. Observe the rules on the packaging.
The situation arises in the event that an abortion was performed. The level of hCG decreases gradually. During the test, a second weaker strip appears. But this does not mean that the pregnancy has been preserved.
After fertilization of the egg in the woman’s body, numerous transformations begin. First of all, concerns a hormonal background. The test will not show the result before the introduction of the egg into the uterus. Strictly speaking, this moment is considered to be the beginning of pregnancy. For all the processes at the initial stage, the hormone progesterone is responsible. Due to its lack of pregnancy may fail, the egg does not gain a foothold, the level of hCG increases more slowly. To test showed a plausible result, you must follow a few rules.
To carry out the analysis only with the morning portion of urine. Even if used modern inkjet test. In this case, the level of hCG will be as great as possible for its duration.
- Use a test with a sensitivity of 10 units. Especially if the delay is up to 1 week. To fix the result, repeat the analysis after a week.
- Choose tests should be quality. Then the probability of a false result is significantly reduced.
- To lower a strip in urine to the specified level. It is enough to withstand 15-20 seconds.
- The result that appears 10 minutes after the analysis is not considered true. Evaluated readings within 5 minutes.
If the situation is alarming, fear, you should consult a specialist. In the blood, the level of hCG increases much faster. Determine the presence or absence of pregnancy can be for sure. In general, pregnancy and menses are considered incomparable.
How does a pregnancy test work
Regardless of the type, all tests are based on a single principle of action. The device contains a reagent that reacts to chorionic hormone (HCG) in the urine. If it is present in a biological fluid, the pregnancy has come.
HCG is a substance that begins to be produced by the shell of a developing embryo from the very first day of conception. Every day the substance accumulates and later makes up the required level, from which the test reacts to the hormone.
The result should look like 1 or 2 clear strips. Modern rapid tests determine the onset of conception as early as 10–12 days from the moment of fertilization.
Why a weak second strip in a pregnancy test - possible causes
The dubious result suggests that the research went wrong.
A similar reaction can speak of various states:
- The onset of pregnancy. Usually a fuzzy streak means fertilization has occurred. The brightness of the reaction depends on the concentration of chorionic gonadotropin in urine. Apparently, in this case, a sufficient amount of the hormone has not been developed.
- Conducting the test in early gestation. When the reagent interacts with low levels of hCG, a not very bright, pale band is visible. A similar result is observed if the woman did an analysis a few days before the menstruation.
- Poor quality rapid test. The purchase of a defective or spoiled device for determining pregnancy is not excluded. It is worth guarding if the stripes look blurry and dull. In the control area should not appear any spots or red strip. Do not forget to check the shelf life of the device.
- Insufficient sensitivity of the rapid test. Modern devices for the diagnosis of pregnancy are characterized by sensitivity to hCG 10-25 mIU / ml. If it is low, the method will show a dubious result at the initial stages of gestation.
- Excess content of biological fluid fell on the test. If a woman incorrectly uses the device without carefully reading the instructions, an erroneous reaction may occur.
- Disturbed menstrual cycle. With various hormonal shifts, sometimes an incorrect result is obtained.
- Condition after a perfect abortion or miscarriage. When after the removal of the ovum from the uterus less than 30 days have passed, the content of hCG in a woman is at a high level, and the strip is hardly visible on the device.
- Drug use to combat infertility containing chorionic gonadotropin.
- Fading pregnancy. When the embryo stops developing, the hormone stops being produced, and the device shows a white stripe.
- Ectopic (ectopic) pregnancy. If the embryo is attached outside the uterus, the chorionic gonadotropin does not flow completely into the urine. A woman notices a second muddy strip, even two weeks after the delay. With the onset of 8 weeks of gestation, signs of “acute abdomen” appear, which may threaten the patient's life.
Violation of instructions as the cause of the pale strip
If you ignore the rules, you can discover the dubious result of the research in the form of a fuzzy line on a rapid test.
The main violations of the rules:
- analysis before the delay of menstruation. Many women rush to learn about the occurrence of pregnancy already in the first day of the absence of the expected menstrual period and get a transparent line in the rapid test. Premature action: the reaction does not have 100% accuracy at the specified time,
- the use of not the morning portion of urine. Doctors say that the urine, which is collected after waking up, contains a high level of human chorionic gonadotropin. Concentrated biological fluid will allow to avoid the doubtful result of the rapid test,
- drink excess water or other drinks. Excessive fluid intake leads to the dilution of urine, which is why urine becomes weakly concentrated. It is not recommended to use diuretics for a similar reason.
- hygiene procedures were not performed prior to testing. Wash the external genitals well and dry them with a towel
- a device for diagnosing pregnancy was in the urine for more than 15 seconds. The inaccurate effect of urine on the reagent may lead to an erroneous reaction,
- time is not respected. After the procedure, do not expect an instant reaction. We'll have to suffer a little and wait as much time as indicated in the instructions (3-5 minutes),
- for the study used dirty and wet capacity. Prepare dry and clean dishes, where there will be urine.
Before using the test, experts recommend that you carefully read the instructions for use to avoid possible errors.
What to do if the second strip is pale
There are several options for what to do when receiving a dubious result of the procedure.
The most common and easiest way is to repeat the diagnosis.
However, the second time you need to take into account all the required rules and factors. Doctors do not advise doing the study on the same day. Wait a few days after the first test to increase the efficiency of the device. If studies re-show a bright or dull second line and raise doubts, try other methods.
- Blood test for chorionic gonadotropin. In the early stages of gestation, the concentration of hCG rises first in the blood and then in the urine. The level of hormone in the blood is higher compared with urine. The study is considered more reliable, because it gives the right results earlier for a period of several weeks. The analysis is allowed to be carried out in the first days of the delay of menstruation or after 20-30 days from the day of the last menstruation. The content of hCG in the blood constantly rises until the 12th week of pregnancy, and then decreases.
- Ultrasound diagnostics. Ultrasound allows the specialist to confirm or deny the pregnancy, as well as to timely identify the existing complications or diseases of the child. The first planned study is assigned to a woman for a period of 10-14 weeks. Sometimes the procedure is carried out before the specified period due to the presence of evidence.
- Visiting a gynecologist. Be sure to come to the doctor. At the first visit, the doctor will ask you the date when the last menstrual period began, the means of contraception used and the presence of concomitant chronic diseases. During the examination, the doctor will confirm or refute the onset of the “interesting situation”. Unlike other diagnostic methods, a gynecologist will be able to determine the period of gestation on examination.
Do not panic when you see the bright line in the rapid test. The exact answer to the question whether there is a pregnancy will be given only by a specialist of the medical institution.
How to get the most reliable result - the doctor advises
To make the procedure correct and the reaction on the rapid test was correct, try to follow the simple steps indicated in the instructions for use:
- buy devices for the diagnosis of pregnancy exclusively in the pharmacy: the only way is confidence that the product was properly stored,
- When purchasing a device, be sure to look at its expiration date to prevent erroneous testing,
- pay attention to the integrity of the packaging: if it is broken, then the device should not be used,
- Do not reapply a one-time test.
- try to use for analysis the first portion of morning urine,
- before the study, conduct a hygienic procedure of the external genital organs,
- open the rapid test just before use.
The doctor tells about the first signs of pregnancy:
Carrying out pregnancy diagnostics with the help of rapid tests, a woman is not insured against receiving poorly visible strips. It is not surprising that when a dubious result appears, the question arises: Has the pregnancy occurred?
It is impossible to say for sure that a poorly visible line precisely means fertilization that has occurred. To make sure in the onset of conception, it is necessary to conduct additional research or consult a gynecologist.
The body's response to pregnancy
According to experts, no woman can accurately indicate early pregnancy. This can be done with the help of the test. However, it will be safer to visit a gynecologist.
However, medicine in the arsenal has accurate symptoms indicating pregnancy.
So the symptoms are as follows:
- Sudden changes in mood. In some cases, the aggressiveness is gaining such intensity that the woman is unable to cope with the emotions that have arisen. Of course, before a woman's monthly period, her mood also changes. However, their intensity is weaker. Mood swings indicate hormonal changes in the female body. This symptom occurs first.
- Other taste preferences. Pregnancy makes adjustments in taste preferences. With the onset of pregnancy, a woman can eat something that she had not eaten before.
- Toxicosis. This symptom is familiar to almost every woman and complicates life in the first three months. As for the brightness and nature of toxicity, they depend on the individual characteristics of the organism. Some women suffer from toxicosis, while others are partially affected.
- Insignificant increase in mammary glands. As a rule, a symptom occurs in women in late pregnancy on the eve of breastfeeding. But some women note changes in early pregnancy.
- Lack of a menstrual cycle. The absence of menstruation indicates the conception of a child. Often, menstruation returns to normal after giving up breastfeeding.
In addition to the main symptoms, pregnancy is accompanied by other specific manifestations. Such phenomena are represented by lack of sleep, malaise and lethargy. In addition, a pregnant woman perceives smells differently and feels a metallic taste in the mouth.
All of the above symptoms even indicate pregnancy, but do not give an absolute guarantee. To confirm or deny pregnancy you need to do a test. In the event that the result is positive, the woman must register with the clinic. The woman has a long 9 months ahead, which will give her parents the meaning of life. The birth of a new man is always a holiday. Ahead of the parents long, sleepless nights and at the same time so happy.
The connection of pregnancy with menstruation
To give the correct answer to the question whether the monthly cycle begins after the test has shown a positive result, it is worthwhile to deal with the processes occurring in the body in women. The main stage of the menstrual cycle is the process of maturation of the egg. If the egg remains unfertilized - it leaves the endometrium. This is called the menstrual cycle.
If the egg has been fertilized, then changes occur in the body, preparing the woman for future birth. All assets the body spends on the preservation of the embryo. During pregnancy, there is a sharp increase in the content of the hormone progesterone in the body. It is responsible for increasing the inner lining of the uterus. Moreover, progesterone prevents contraction of the uterine muscles.
From the foregoing, it follows that menstruation and pregnancy - although it is interconnected, but rare. However, there are cases when the test shows 2 strips and the plan began the menstrual cycle. What is the reason?
According to scientists, menstruation in the first months of pregnancy is an acceptable phenomenon. Most likely, the egg cell was fertilized in the middle of the cycle, as a result of which the organism did not regroup. This results from the fact that the ovum did not manage to reach the uterus and to gain a foothold in it. As a rule, the process takes from 5 to 14 days. Normally, the next month should not be accompanied by monthly. In that case, if the bleeding has reappeared, then this is a reason to go to the gynecologist.
Some women are not aware of pregnancy due to the fact that the menstrual cycle goes on schedule. So, what are the main reasons:
- Hormonal imbalance. If the test result showed 2 strips and the menstruation came as planned, then most likely there is a shortage of the main female hormone, progesterone, in the woman’s body. Women report a low intensity discharge. Taking into account the unstable hormonal background of women, menstruation can be observed during the first trimester, while involving the second. To eliminate the problem, a course of drugs representing an analogue of progesterone is prescribed.
- The presence of 2 eggs. Due to this, the maturation of the egg occurs in parallel mode. However, only one is fertilized while the second leaves the female body.
- Unfavorable location of the egg. In that case, if the egg is located in a dangerous place, it will affect the process of blood circulation. Such violations can lead to egg rejection.
- Fading pregnancy.
Каждая из вышеперечисленных причин может привести к прерыванию беременности, которая сопровождается мазней. Во избежание развития подобного рода проблем женщине назначается курс терапии.
Of course, there are other reasons why the menstrual cycle begins with a positive test result. Other reasons are not classified by experts as dangerous. In this situation, the menstrual cycle begins at a certain point. It is worth noting that the cycle is characterized by different intensity and duration. As for the duration, it can vary within one day or several days.
What needs attention?
First of all, a woman should throw panic aside and tune in to a positive outcome. A woman should not leave monthly during pregnancy without attention. To underestimate the seriousness of daub is stupid. After all, the future child depends on it. Any anomaly indicates violations. In this situation, violations can trigger the activation of the process of rejection of the ovum.
How to recognize a miscarriage?
Non-hazardous secretions are caused by active movements that disappear at night. Dangerous situations are represented by discomfort, drawing pain in the lower abdomen. If the future mommy has a fairly strong immune system, then it is likely that the body will be able to cope with the problem.
How to find out if pregnancy has come or not?
The first suspicions about pregnancy arise in a girl when she realizes that she has a “delay”. But since delays can be for various reasons, the girl decides to check whether the delay is related to the pregnancy on her own.
For these purposes, specialized tests are sold in pharmacies, they come from different manufacturers and are sold at different prices. But the method of determining pregnancy is the same for everyone, and involves urinalysis for the level of hCG in the body at the moment.
Make a labor test is not up. It is necessary to collect urine and lower the test into it. Next, wait 10 minutes, and the result will show the presence or absence of pregnancy.
The presence of pregnancy can be assumed if the test result showed two strips. If the strip is left alone, then, most likely, the pregnancy has not come or very little time has passed since the moment of conception.
However, there is another option that the test can show. The second strip on the test seems to be there, but it is barely noticeable.
What can mean a weak strip in a pregnancy test
Find out what the weak second bar means; information on how the test works will help.
The principle of operation is based on the reaction of the reagent, which is applied to the test. If the level of hCG (a hormone produced during pregnancy) rises in the body, the reagent becomes colored and a second strip appears.
The number of hCG during pregnancy increases every day. If non-pregnant women, the HCG index is from 0 to 5, then already in the first weeks the level of the hormone shows a value from 25 to 156.
Usually, the instructions say that reliable results can be expected from the first days of the delayed menstruation. However, first of all, it is worth being guided by what concentration of hCG the reagent is designed for.
But before you take for granted the test results, you should find out exactly how the second bar should look.
- To make sure that you do not conduct the test too early, read the information in the instructions: on what day is the test to be held,
- Follow all recommendations for proper testing,
- Exclude options when the test can show elevated levels of hCG and does not mean pregnancy.
If you suddenly showed a pale strip on a pregnancy test, then this may have such reasons:
- If you do a test in the early stages, then the readings may well be inaccurate or the strip will be very weak, because the hormone level is not high enough. In this case, it is worth repeating the test in a week,
- Sometimes there are substandard tests, expired or with poor reagent application. Do not rely on the testimony of such a test. Pay attention to the expiration date of the test. If you have doubts about the quality, take a test from another manufacturer,
- It so happens that the girl really wants to get pregnant, and then she sees the second strip where there is none. She begins to peer into the control field. On some tests, it is indeed possible to see the second applied reagent strip even before the test begins. The reagent is slightly darker than the white field of the control zone. But the real second bar should be much more intense anyway

Monthly run out, take another test, it just does not lie, but just do you may be pregnant, it happens, washing the fetus called.
tests may lie, there may be periods even during pregnancy (so it was with me). Go to the gynecologist, do a vaginal ultrasound - then everything will become clear
usually in posit side tests don't lie
as a doctor, I say that this is normal, there is no pregnancy, the level of hgch (the same test with stripes that you do at home, that is, it shows the level of hgch) and so before menstruation it also rises slightly and the weak strip will be!
You are not pregnant. Take another test if you are not sure. In general, it is possible that the egg cell was fertilized, but it did not attach, so the menstruation went, it did not even reach the miscarriage as such, but simply “did not work out”.
Thank you all for the answers. The main thing is that there was nothing bad, otherwise I’ve already read a lot on the forums. In a few days I will do another testic for sure.
Now, for the sake of interest, I looked at those tests - on two different weak second strips, but not on today's one. And still pulls the waist constantly, although earlier menstruation did not bother me. I can not calm down, some fears (
usually in posit side tests don't lie
I, too, lied to the positive side, I put 3 tests in the negative, and put the 4 tests .. But there was nothing))
Most likely you can be congratulated. To be sure - donate blood for hCG!
Most likely no. I was like that too. And it was not a pregnancy.
So as not to be lost in conjectures, create blood on hchg.
The author, well, how are you doing, what was it in the end? I have exactly the same situation now, very worried. Pozh, write off! I will wait :-)))
girls, this situation. The delay was 20 days.
In the beginning, I made 2 events - negative.
Then she made a secret - also negative.
Yesterday I made an evitest - ofigel. Weak second strip.
today I repeated the weak second strip again, but after about an hour and a half the periods began. I hope Guest 4 answer is true, and there is no pregnancy. Just before the monthly showed.
+ my wisdom tooth is growing, it hurts terribly, I can't eat anything. maybe because of this pain and nerves there was a delay.
Oh, yesterday and today I did frautest and not evi.
by the way somewhere half a year ago, saw postinor.
then treated for thrush (flconazole)
but now I drink nimesil (pain reliever)
Maybe these drugs somehow influenced the menstrual cycle.
so what did you have?
I appeal to you with the following question: I became ill on October 16, I thought I was poisoned, but there were some discharges from my chest, I thought Prolactin improved, I passed the analysis and Prolactin 92, waited for menstruations, but they did not come. with a delay of 6 days. At the moment, monthly are already 7 days and very abundant. My pituitary macroadenoma is taking Dostinex for the second year. What happened with me?
Girls, I have such a situation, all my tests have shown a positive result, but all are not very bright, we do not protect ourselves with my husband, but the older daughter still sucks the milk is not bitter, can these tests talk about pregnancy
The delay was 2 days in the morning. I made a test. The 4th strip showed a barely visible second strip! And on the same day my period came in. On the first day my stomach ached and I cut now my period goes as it should be! Nothing hurts! I was glad I thought I was pregnant I don’t know what to do and what to think! what do you think it could be?

How do tests work?
Pharmacies sell all sorts of tests to determine pregnancy at home. They differ in the method of conducting research. To use each of them it is necessary to study the features of their application.
Among the tests for pregnancy are distinguished:
- Test strips. They are the cheapest means for determining pregnancy. To use them, you must take the container in which the urine portion is collected. After opening the package, the test is lowered into the container to the drawn border for no more than 5 seconds. After this test must be placed on a horizontal surface. You can evaluate the result after 5 minutes.
- Tablet Tests. The principle of their operation is similar to the work of the test strip. Only in this case, the test does not fall into the container, and a drop of urine is applied to its surface using a special pipette. After the substance is distributed over the surface, the result is shown in the second window of the tablet.
- Inkjet tests. During their conduct, the strip is placed under the jet for a few seconds. After the distribution of the substance in the special window reflects the result.
- Electronic tests. They are the most expensive and reliable means of determining pregnancy. Electronic tests work on the jet principle. In this case, the main difference is the speed of appearance of the result. Some types of tests even determine the expected duration of pregnancy.
All tests are designed to detect pregnancy hormone in a woman’s urine. A special reagent is applied to the surface of the dough, which is colored when a sufficient concentration of the hormone in the body is reached.
The level of hCG depends on the duration of pregnancy, increasing after the onset of fertilization. Every two days, hCG doubles. The hormone enters the body of a woman as a result of its production in the shell of the chorionic embryo. The first “doses” can be detected as early as a week after fertilization.
In the presence of a hormone in a woman’s body, instead of the standard single strip, a second color line appears.
At the same time, some factors may affect the reliability of the result:
- conditions of storage and transportation of dough,
- shelf life,
- research methodology,
- the presence of diseases in the female body.
To get a reliable result and not see the missing or second pale strip on the test, it is worthwhile to find out some reasons for the manifestation of an ambiguous reaction.
Pale strip on the test in the absence of pregnancy
Sometimes a woman may see a pale strip on the test. In this situation there may be several options for the development of events. An important condition for evaluating the result is the correctness of the testing procedure.
Test makers attach detailed instructions to the product. It indicates how long it is necessary to lower the test strip into the container, how much to keep the test under the stream of urine, and after what time it is necessary to evaluate the result.
Sometimes, even with the right application, a woman can find an ambiguous result. This may result from an uneven impregnation of the surface with urine. Distribution most often occurs with errors on the test strips. In this case, you must repeat the procedure using the tablet test.
The second common reason for the appearance of a dubious result is the early use of the test. Manufacturers recommend to carry out the diagnostic procedure no earlier than the first day after the onset of the monthly delay. Read more about when a pregnancy test shows the result →
Some tests indicate that they can be carried out before the first day of delay. Usually these tests have an increased sensitivity. However, they can also give a false-positive or false-negative result. In this case, the second strip may not appear at all or have a weak, blurry outlines. Therefore, it is necessary to conduct a test when a delay occurs.
Manufacturers note that the second strip should be the same with the control: smooth, bright, and have clear edges. In length and width, it should coincide with the first strip. Only in this case the test is positive.
However, it is possible to talk about the onset of pregnancy after the laboratory analysis to determine the hCG hormone in the blood. It is carried out at intervals of 2-3 days to assess the growth of indicators.
A pale second strip on the test may occur after the deadline for evaluation of the result. Sometimes women check the drawing on the test half an hour after the study. In this case, this result cannot be regarded as positive: reagent residues may appear in this way.
Sometimes this result can give a test conducted after treatment for infertility. In the course of treatment, a woman takes drugs that contain a small dose of the hormone HCG (Pregnili, Profazi). In this case, it may not be removed from the body for some time.
A positive test with a pale second stripe may indicate the presence in the body of a woman of certain diseases. Often, cells similar to the hormone produced by the chorion of the ovum, are formed in the presence of fibroids, cysts. After the examination, doctors can diagnose uterine chorionepithelioma, vesicle drifts.
When pregnancy is possible with such a reaction test
A second strip of pale color may appear immediately during the test. In this case, pregnancy may be suspected. However, an accurate assessment can be given only after the examination in a medical institution so that disappointment does not occur in the event of a false positive result.
The second pale strip on the test may indicate a low content of the hormone HCG in the urine of a woman. This result can occur for several reasons:
- If the gestation period is very small, but there is still no delay, then the strip may have a pale color.
- When using the means for removing excess fluid from the body (diuretic drugs), the urine is diluted. Also, a low concentration of the hormone can occur due to the use of products that affect the urinary function, and with increased kidney function.
- A weak second strip may indicate abnormalities in the development of pregnancy.
- In the case of missed abortion test may show a weak second strip.
- For ectopic pregnancy, the test response may be mixed.
- If the test is carried out in the period after the procedure of abortion (abortion, miscarriage, curettage), then the test may be positive. In this case, the presence of the hormone hCG is due to its incomplete excretion after a recent pregnancy.
What if the test shows a pale second strip?
Ambiguous results can not be reliable to determine the presence of pregnancy. Therefore, retesting is necessary. You can use a different brand of dough, or buy it at another pharmacy.
However, doctors advise the examination using laboratory methods. The most effective is the analysis of the determination of the hormone hCG in serum. He gives up on an empty stomach in the morning. By the amount of its content, you can determine whether a pregnancy has occurred. Also, its level should approximately match the rate of its concentration in the blood in accordance with the gestational age.
If a woman has pain in the abdomen, an urgent gynecologist consultation is necessary. He will be able to confirm or deny an ectopic pregnancy.
In any case, if a woman saw on the test for determining pregnancy only a barely noticeable second strip, it is too early to rejoice. It is necessary to confirm the result using other diagnostic methods and only after consulting a specialist.

All pregnancy tests have the same principle of action - they react to the presence of chorionic gonadotropin in the urine. If present, the test always gives a positive answer in the form of two strips. The questionable result means that there is uncertainty about the presence of the second strip. It may be barely noticeable, blurred, or shine through a bright light. Causes: insufficient amount of hCG, bordering on the minimum, but affecting the sensitivity of the test, defective test, incorrect use of the test, a strong desire of a woman to get a positive result. The latter situation is more common. What if the test shows a questionable answer? Repeat it after 48 hours, and better - 2 days after the delay.
Causes of a weak second band on the test
If the second band on the test is barely noticeable, then this may indicate both a false positive result (no pregnancy, but the test will determine it) and a false negative result (there is a pregnancy, but the test does not recognize it).
Possible reasons for the incorrect operation of the device are as follows:
A woman is pregnant, but she is conducting the test too early. In this case, the content of human chorionic gonadotropin in the urine does not reach the level necessary for the test to fully respond.
The test itself was of poor quality. A weak band on it may appear when the device is expired, defective, or stored incorrectly. Especially, a woman should be wary when both bands are blurred or weak. There may be spots on the dough or strip formation in the wrong place - all these are signs of damage to the device.
The sensitivity of the test has a low threshold. The result will be the more reliable, the higher the sensitivity of the test to HCG. Modern devices are able to capture the hormone in the urine, ranging from 10 mIU / ml. The most “unreliable” in this regard, it is inexpensive strip tests that have a sensitivity of 25 mIU / ml and with early diagnosis of pregnancy often give a dubious result.
Too much or too little urine fell on the test. If the test in the urine overexposure, it can lead to the fact that the reagent just blurred on the strip, and it will be fuzzy. When a woman fails to pass the urine test, this will make the hCG hormone insufficient for complete staining of the second band.
Unstable menstrual schedule. In the case when the monthly cycle of a woman is unsteady, she can conduct a study too early, which means that it will not be enough to get a clear result of hCG in the urine.
Late onset of pregnancy. This reason is also associated with too early research. Sometimes it happens that ovulation is somewhat delayed. As a result, fertilization of the egg does not occur in the middle of the cycle, but closer to its end. Naturally, menstruation does not occur, but the chorionic gonadotropin in the urine is still not enough for the test to be able to "examine" it well.
Recently postponed abortion. If a woman has an abortion a few weeks ago, then chorionic gonadotropin continues to circulate in her body. Gradually, its level decreases, but a sharp decline cannot occur. Therefore, the test, carried out at 4-30 days after an abortion, will produce a weak second strip, although in fact there is no pregnancy.
Taking drugs with hCG. Some medicines contain chorionic gonadotropin, for example, tablets for the treatment of infertility (Pregnil, Profazi, Novarel and others). Even after the end of the therapeutic course, their components may linger for some time in the body and lead to the appearance of a weak second strip on the test.
Trophoblastic diseases, such as chorionepithelioma of the uterus, increase the level of hCG in the blood and urine, which can provoke the appearance of a pale band on the test, despite the absence of an embryo. Sometimes this result can be obtained with uterine myoma, an ovarian cyst, or a vesicle drift.
The presence of ectopic pregnancy. Often it is during ectopic pregnancy that the second band on the test appears weakly. The body produces chorionic gonadotropin, but in insufficient volume, so the device can not give an adequate response.
Fading pregnancy. In this case, the woman's embryo is preserved in the uterus, but it has stopped its development. Accordingly, the rate of hormone production fall, which can lead to the appearance of a weak strip on the test. A woman should be alerted by such signs as abdominal pain, the appearance of bleeding, lack of menstruation, fever.
Climax. Sometimes, during menopause, a woman’s hormonal gonadotropin level in the blood and urine rises due to hormonal disruption. This may cause the test result to be questionable.
Kidney disease. If a woman has pronounced disorders in the functioning of the kidneys, then this may lead to the fact that hCG with urine will not be excreted sufficiently. Therefore, the test in this case often responds to the presence of pregnancy with a weak second band.
Test manufacturers note that the presence of a weak band on a test should be considered a positive result.
Nevertheless, it is recommended to conduct a control study using a new pregnancy test. It is best to do this after a few days. If the second test produces a bright and clear band, the result can be considered positive with certainty. When the strip on the test is again weak or blurred, you should consult a specialist. Indeed, often such test results may indicate health problems.
How to get the most reliable result?
To test the results were as accurate as possible, it is necessary to familiarize yourself with the instructions for applying the test and strictly follow it.
Observance of simple rules of the procedure will help avoid the appearance of a pale second band on the test and unambiguously interpret the result:
It is best to conduct the test procedure no earlier than the first day of the delay of menstruation. Some doctors do advise to wait at least 5-7 days from the expected date of the beginning of the month. The sooner the pregnancy is diagnosed, the less chance that the result will be 100% reliable.
To perform the study it is necessary to take only fresh urine. Well, if you can perform the procedure in the morning, immediately after waking up. At this particular time, the concentration of chorionic gonadotropin in the urine will be maximum.
If the procedure is scheduled for the evening, then during the day you need to abandon the use of too large volumes of fluid. Also on the eve of the study, diuretics and any other drugs with a diuretic effect should be avoided.
The time of urine exposure to the test should not be less than 5-15 seconds (according to the instructions for use).
Before the procedure, you need to take care of the cleanliness of the container for collecting urine and external genital organs.
Evaluate the result should not be earlier than in 3-5 minutes. Until this time, the second strip (if it appears) may remain weak and dim.
Is there a pregnancy if the second strip is pale
A pregnancy test shows the presence or absence of pregnancy by the presence of one or two strips, respectively. However, is there really a pregnancy if the second strip is pale. There are many such cases and when one of them happens to a woman personally, a lot of doubts immediately arise about the reliability of the test.
Both strips on the test can be bright only if the test occurs only after five days of delay. If you try to determine pregnancy before this period, the stripes may be pale and even barely visible, but this does not mean that the result is negative.
The presence of color and brightness of the strip is influenced by hCG - a special pregnancy hormone and its concentration. If it is too small, then the strips will be pale. The reason for the weak color of the strips can be the problem of the kidneys or a large amount of fluid consumed.
Gynecologists recommend purchasing a more expensive and modern pregnancy test, which will be able to show a clearly defined number of strips even at low hCG levels, and also be checked by a doctor personally to confirm the test result, since each woman can only be individualized.
Do two stripes always mean pregnancy
When it becomes necessary to determine a false or positive result of pregnancy, many prefer to get an inexpensive pregnancy test, believing that if destined, then any identifier will show a reliable result. When two strips appear, many people start to panic, others rejoice, but do two strips always mean pregnancy? In order not to remain a moment in doubt, it is necessary to assimilate the simple truth that no pregnancy test, no matter how expensive and up-to-date it turns out, will not be able to determine 100% of pregnancy.
Of course, it is still worthwhile to be on our guard and it is better to do a repeated test in a week, since its reliability increases significantly. The control examination should be carried out by a gynecologist, who will examine the woman and prescribe an ultrasound scan, where the presence of the pregnancy and its exact term will be clearly visible.
The causes of false positive results of pregnancy consist of many factors, based on the lifestyle of a woman, her sex life, the presence of abortions and taking all kinds of drugs. All tests show the presence or absence of pregnancy by 97%, the remaining 3% is always kept in stock by the doctor.
What principle is based on the effect of tests
After the release of the egg from the follicle, the level of chorionic gonadotropin begins to grow steadily.
During fertilization, an increase in the concentration of the hormone occurs every 2 days 2 times. Identify the indicator of hCG in the urine and blood of a woman.
Each pregnancy test contains specific antibodies that respond to the presence of hCG. In the area of their presence staining of the strip occurs after exposure to urine.
The reliability of the result is achieved by increasing the concentration of hCG to 25 mIU / ml.
Already after 1-2 weeks after conception, the hormone content in the woman’s body is 25-100 mIU / ml. Therefore, in most cases, you can determine pregnancy 1-2 days before the delay.
To minimize the risk of error, it is recommended to conduct 2 tests. Currently, in any pharmacy kiosk you can buy 4 types of dough:
It is the cheapest th option. However, the sensitivity of this test is low in comparison with analogues.
th option. However, the sensitivity of this test is low in comparison with analogues.
The most common cause of the error is insufficient saturation of the indicator window with liquid.
The tests look like paper strips, which should be lowered into a container filled with urine. A positive result is the appearance of 2 colored stripes.
The device has 2 windows. When urine enters the first “window”, the result appears in the second.
The cost of the tablet test is higher, as is the guarantee of an accurate result.
The highest quality and expensive test.
The principle of action is based on the interaction of particles of a special substance with hCG, which allows to know the result after a minute. To diagnose pregnancy with a jet test, it is not necessary to collect biological material in a separate container.
It can be lowered into a glass with urine or used on the principle of jet tests.
Such a gadget on the electronic scoreboard will write “+” if the pregnancy is confirmed and “-” if there is no pregnancy.
Some electronic pregnancy tests may have advanced features. For example, the Clearblue test also shows the gestational age from conception.
The advantages of modern methods are indisputable. There is no need to interpret the clarity and color of the strips, you can find out the result at any time, as it remains and does not change under the influence of external factors.
Reliability of results
The probability of error when using test strips depends on the shelf life, the correct execution of the procedure, the individuality of the physiological processes in the body. It is advisable to acquire tests from reliable manufacturers.
Often a weakly expressed test is a direct consequence of a violation of instructions.
The analysis of morning urine has the highest confidence, which should be collected immediately after awakening.
If this is not possible, you can store the urine for several hours in the refrigerator.
Accurately determine the pregnancy in the early stages before the delay of menstruation allows:
- The leader is the FRAUTEST line.
The company Human Gesellschaft once again confirms the German quality. Almost all types of tests are presented on the modern market of pharmacological products. At the same time, even low-cost options are very accurate and sometimes they can diagnose pregnancy several days before the delay.
Frautest DOUBLE CONTROL strips, 15 mIU / ml have high sensitivity.
- BB test strip with a sensitivity of 10 mIU / ml, as well as a BB-suite, is produced by the French company Innotech International.
- The Swiss company SENSITIVE ECONOM supplies TEST for BEST No. 10 to Russia, also designed to diagnose pregnancy before a delay.
- Highly sensitive tests include test strips of the latest generation Home Test Express, USA, which allow to determine the level of hCG, starting at 10 mIU / ml.
The range of tests for the early diagnosis of pregnancy is quite wide.
Unfortunately, the rest of the Russian-made tools often fail. Therefore, the most accurate result is obtained using products from a foreign manufacturer.
The reason for the appearance of slightly colored second strip on the test for determining pregnancy
Sometimes a woman doubts conception, since the strip on the test is poorly visible. However, with a normally developing pregnancy, inexpressive coloring is possible for several reasons.
- The test was conducted until the delay of menstruation.
In this case, the increase in hCG is not enough to accurately determine the conception. Therefore, the strip and it turns out slightly colored.
For the reliability of the result, a second diagnosis should be carried out after 2-3 days.
- If ovulation is late.
In this case, the production of HCG begins later. The causes of late ovulation are premenopause, gynecological diseases, an imbalance of pituitary hormones, and frequent stress.
Late ovulation may occur within 3 months after abortion or 1 year after giving birth.
- If hormone therapy is carried out.
Against the background of the use of hormonal drugs, an increase in hCG may look weak. In this case, the second strip on the test will be paler. In addition, a false-positive test is present if it is performed earlier than 2 weeks after the embryo has been transplanted into the uterus.
- If the embryo stopped developing.
There is a slow decrease in the concentration of hCG in the body of a woman. Therefore, if the test shows a weak second strip, this may indicate a missed abortion. As a rule, the suspicion of missed abortion is confirmed if, after 3 weeks after ovulation, there is no clear color on the strip.
In fact, the pathology can also be accompanied by the normal production of hCG.
To determine ectopic pregnancy in the early stages only with the help of the concentration of human chorionic gonadotropin is impossible.
Необходимо учитывать характерную симптоматику и результаты обследования аппаратными методами.
Порой при внематочной беременности производство ХГЧ нарушается, так как отсутствуют оптимальные условия для развития оболочки эмбриона. В этом случае тест может быть ложноотрицательным.
- Неисправность самого теста.
When purchasing a product, you need to pay attention to the specified expiration date and package integrity. Much also depends on the conditions in which the test was stored.
For example, the test should be stored at a temperature of 2-28 ° C, and used after heating the product to room temperature. When in the refrigerator, the test loses its qualities.
- Some types of oncology.
Thus, chorionic carcinoma or vesicles, oncology of the intestines, as well as organs of the urogenital system are accompanied by an increase in the concentration of hCG.
Normally, the level of human chorionic gonadotropin does not exceed 5 mIU / ml. If you identify a high value and the absence of pregnancy, you should definitely perform a thorough examination.
- Spontaneous abortion or abortion.
If parts of the ovum remain in the uterus. A decrease in the level of hCG occurs gradually, and the test may show a false positive result.
In total, I had 7 pregnancies - two of them ended in miscarriages, one was ectopic. After conception, in all seven cases I did a pregnancy test. Some were at the beginning of the menstruation cycle, others after a delay.
In cases where the test did before the delay, the indicator showed a weak strip. After menstruation, sometimes there was a weak strip, in other cases, bright, clear. But I will make a reservation that the test showed a pale pink color after menstruation only when an ectopic pregnancy was confirmed. During normal pregnancy, the second strip on the test was painted in a bright saturated color.
For all four "normal" pregnancies (I am now fourth pregnant), the test can show the intensity of the color at the expense of the term itself. If you suspect pregnancy, but have not yet gone on an ultrasound, and the test showed a pale pink strip, it is better to be safe. In my case, I discovered ectopic.
It is better, of course, to repeat the test in two weeks, if you are recorded on the ultrasound at all in a month. The more weeks you have, the brighter the indicator should be. If he still remains pale, you need to sound the alarm. Most likely, the pregnancy has come, but the fetus has either died or an ectopic pregnancy takes place.
The main thing is if there is a suspicion of delay, if there is no pain, the pale strip on the test indicates only a short period. Either you are not pregnant, but the test is defective (which still needs to be confirmed on ultrasound and according to analyzes).
Even with the appearance of strips of pale color, the pregnancy test should be regarded as positive. This is a reason to visit gynecology. Further diagnosis with the use of blood sample analysis and ultrasound will help confirm pregnancy.
