When does a pregnancy test determine it? On what day will a pregnancy test show a positive result? Pregnancy and pathologies: what the test will show

Most women try to find out about their pregnancy as early as possible. The reasons for this interest are different for everyone. But curiosity takes over, and they try to quickly acquire special tests. First of all, you need to understand how they work, and then decide when to take a pregnancy test?

How does a pregnancy test work?

A pregnancy test works on the principle of detecting human chorionic gonadotropin (hCG). As a rule, the sensitivity of tests is no more than 25 mIU/ml. HCG begins to be produced after the embryo attaches to the uterus. Moreover, the level of this hormone doubles every day. Therefore, if ovulation took place on the 12th day of the cycle, then the fertilized egg is implanted after 8 days.

HCG begins to rise from the 20th day from the beginning of the previous menstruation. At this time, its level is 2 mIU/ml, on day 21 – 4 mIU/ml. Every day its number doubles. As a result, on day 24 hCG level exceeds 25 mIU/ml. This is exactly what a pregnancy test can record. But there are products that detect 20 mIU/ml. However, you need to understand that ovulation can occur on the 14th, 15th and other days of the cycle. In addition, the journey of a fertilized egg to the uterus may take not 8, but 10 days.

In order to do the test, you should wait a few days after the delay. By this time, the female body will have produced a sufficient amount of human chorionic gonadotropin, which can be determined in urine using a test.

Most products state on the packaging that they are 99% accurate and can be performed on the first day of the delay. But scientists have proven that this statement is not true. Thanks to research, it was found that out of 18 pregnancy tests, only one is sensitive enough to determine the level of hCG that occurs on the first day of the delay in many pregnant women. Other tests were able to detect pregnancy at this stage in only 16% of cases.

However, if ovulation was early, you can find out if you are pregnant even before your menstruation is missed. At this time, the test may show a weak second line. And with late ovulation, in the first few days of the delay it will show only one stripe. Therefore, if the result is negative, experts recommend repeating the test in a couple of days. Also, women wonder whether to take a pregnancy test in the morning or evening? The highest concentration of hCG is observed after sleep. Therefore, the test must be done on morning urine.

In addition, before diagnostics, you need to check the expiration date and tightness of the packaging, since the test will deteriorate due to moisture. First you need to read the instructions, because different brands of tests can be used in different ways.

Effect of time of day on pregnancy test use

Almost all women try to quickly find out if they are pregnant. But in the early stages, it is advisable to fully follow the instructions for the test. When taking a pregnancy test, it is worth remembering that the concentration of hCG in morning urine is higher, and, therefore, the accuracy of the result is much higher.

However, if there is a long delay, this test will show pregnancy both during the day and in the evening.

• But you still need to comply with some conditions:
• A pregnancy test should only be performed on fresh urine. Before the test, you should not take diuretics or eat watermelon, otherwise the urine will be diluted and an incorrect result may be obtained.
• Before the diagnosis, you should not urinate for three to four hours. During this time, the urine will be able to concentrate.
• In some cases, the reliability of the product is influenced by the conditions and shelf life of the test.

Also, before conducting the test, you must carefully read the instructions for it.

Compliance with all the above conditions increases the reliability of the result.

Questionable pregnancy test results

• Sometimes pregnancy tests show questionable results. This can happen for a number of reasons:
• too early diagnosis (even if pregnancy is present, the test will show a negative result);
• violation of the rules for using tests prescribed in the instructions;
• use of low-quality tests;

the presence of diseases that increase the concentration of hCG, or the use of drugs containing this hormone.

It is worth noting that a negative result does not mean the absence of pregnancy. Therefore, if menstruation never occurs, experts recommend repeated diagnostics. It is also advisable to consult a doctor for an accurate diagnosis.

How and when to take a pregnancy test correctly?

The article will describe what how to take a pregnancy test, and what types of tests are common. Pregnancy is a wonderful time, but before pregnancy, people often have to worry. Someone is worried about an unexpected situation for which people are not prepared.

People who use tests can be divided into two groups:

1. Those who are worried about the thought of pregnancy;
2. And those who are waiting for the event and want to see the two coveted stripes.

Humanity knows four types of tests :

1. Strip- This is the most common type, which is in demand among people because of its low price. On average, they cost no more than twenty rubles;
2. Electronic test– one of the modern and reliable ways to confirm pregnancy. The tests are classified as reusable; they have a small display indicating the week of pregnancy;
3. Jet test– its technology is slightly different from all others. The kit comes with a small substrate where you need to drop urine using a pipette;
4. Tablet test– the most modern and convenient way to carry out the procedure. You need to direct the strip under the stream and look at the result.

How is pregnancy determined?

All tests follow the same principle: they detect the presence of a fetus based on the level of the hormone hCG. When an embryo is born inside a woman, the level of the hormone constantly increases.

Cheap and low-quality tests do not always determine the presence of a fetus, especially in the early stages, due to low hormone levels.

What time to take a pregnancy test?

The procedure must be followed early in the morning and try to collect a medium portion of urine. At this time of day it contains the maximum amount of the required hormone. To dispel doubts regarding pregnancy, it is recommended to do the following:

1. Sterilize the container;
2. Wash your hands and intimate areas;
3. Start urinating into the toilet;
4. Place the container under the stream;
5. Lower the strip to the mark;
6. Place it on a dry surface;
7. After three minutes, evaluate the result.

The technology of execution is simple, and any girl can perform the procedure. We would like to say once again that for the purity of the results the test must be done in the morning.

When to take a pregnancy test after conception?

Undoubtedly, pregnancy is a happy time, and even those people who were not expecting this event understand that children are the most precious thing that God can give. But before the children come, to the expectant mother you need to go through several complex and exciting procedures. And the first thing parents who are expecting a new addition to their family have to overcome is conducting a test and confirming their hopes.

How soon to take a pregnancy test Is it necessary after conception? The procedure must be carried out after a missed period. Get true information possible if the delay is more than ten days.

But there are tests that can determine the correct result after the first days of delay- this is what their manufacturers say.

If the test shows two lines, then two days later it is recommended to do it again; if the result is the same, then it’s time to go to the doctor and register for a consultation.

If the delay is more than two months, then if you are pregnant, every test will tell you about it. If this does not happen, you should consult a doctor.

Are the tests wrong?

Tests to make mistakes. A positive result occurs in the following cases:

• Pregnant woman;
• For kidney diseases;
• Recently terminated pregnancy;
• Ectopic pregnancy;

An erroneous result may occur due to incorrect use or malfunction. On each of the strips one red stripe is visible, which indicates that the device can be used and is not defective. Before the purchase you need to pay attention to the expiration date.

A negative result may occur in the following cases:

• Insensitive item;
• Short term;
• Low hCG levels;
• Lack of pregnancy;
• Defective goods.

To perform the test correctly, you need to read the instructions for use, which should be in each package.

• Take a strip carefully, with your fingertips, without blurting, her;
• If you can see faint pink stripe, then this may be a symptom of a miscarriage;
• Worth collecting for analysis fresh urine;
• Before the procedure don't drink a lot;
• It is better to use modern and expensive tests;

The article discussed how to take a pregnancy test, what time is best to take it in order to achieve the most correct results, and what recommendations should be followed.

If the test still gives a positive result, then it’s worth starting.

Modern tests make it possible to determine pregnancy as soon as possible after “suspicious” sexual intercourse. But this cannot be done earlier than is possible in principle. And in order to correctly answer the question posed, it is necessary to understand the processes that occur after the meeting of the sperm and egg.

How does a pregnancy test work?

So, we know that after fertilization has occurred, the level of the hCG hormone in a woman’s blood begins to increase, which indicates the presence of pregnancy. Having identified this substance, the test shows us a positive result - two stripes. In fact, the test reacts to the presence of the hormone gonadotropin in the urine: when the level of hCG rises, a reagent appears on the second test strip.

HCG in the body of a pregnant woman is produced immediately after implantation of the embryo into the wall of the uterus, first in the blood, and a little later in the woman’s urine, and it is usually found in a lower concentration in the urine than in the blood. Implantation, in turn, occurs 7-10 days after ovulation. But it must be taken into account that the level of the hormone grows gradually, increasing daily until it reaches a certain level, which the test is able to record. This moment determines the time frame. That is, the test is able to “detect” the presence of the hormone gonadotropin in the urine of a pregnant woman no earlier than 11-15 days after the day of the last ovulation. The lower the sensitivity threshold of the test, the earlier it can detect pregnancy and the more expensive it costs. Tests with a sensitivity of 10 mIU/ml (as a rule, belong to this category) are able to determine an existing pregnancy several (up to five) days before the expected period. Tests with a sensitivity of 25 mIU/ml (in the form of strip strips) determine pregnancy starting from the first day of delay. But these are statistics. And there are also individual cases with early or late implantation. Therefore, a premature test can often be wrong.

When to take a pregnancy test if you have an irregular cycle?

The likelihood of a test error is especially high if a woman has an irregular menstrual cycle. A test carried out ahead of time in this case may show false negative results, because the gestational age may be too short for the reactive strip to work. A pregnancy test error is more likely the earlier the test was performed.

How to take a pregnancy test correctly?

Regardless of the regularity of the cycle and other characteristics of the female body, the reliability of the test will be higher, the more clearly the rules for its conduct are followed. Any violations of the instructions may cause false results.

It is believed that a pregnancy test in the morning shows the most reliable results, since the concentration of hCG in morning urine is the highest. But if the delay is already long, then the test can generally be carried out at any time of the day.

A prerequisite is compliance with the rules of sterility: no foreign substances should enter the test liquid, and therefore hands must first be thoroughly washed and wiped dry. Also prepare a sterile vessel for collecting material in advance.

The test strip must be immersed in a container with urine only to the level indicated on its strip, and always on the side indicated (where the reactive substance is contained).

You should not evaluate the test result earlier than the time specified in the instructions (usually 5 minutes) or much later. After a long period of time, the results of any test are no longer valid.

For the first pregnancy, the test showed a positive result on the first day of the delay. On the second only on the 5th, on the third I didn’t show it at all for a long time, I donated blood for hCG and found out. The children are all healthy, praise be to the Almighty

From Guest

And the test showed me two and one very weak one during the first pregnancy, after my period and it was 5 weeks)

From Guest

And I took a test at 3 weeks of pregnancy and showed a negative result, 10 days later I donated blood for hCG and in the end the period was 5 weeks)) And now I’m 8 months)))

From NastenkaYour

I took a test on the 7-10th day of the delay, I don’t remember exactly, it showed everything clearly, it was just 6 weeks from the month. and from the estimated conception 4 weeks.

From Guest

I am now 4 days pregnant, my husband and I really want a baby. I took the test 2 days in a row in the morning and it was negative, we’ll wait a little longer...maybe in 2-3 days it will show 2 cherished stripes :-)

From Guest

There is a delay of 5 days. I took a negative test, but the delay continues, I will do another test later. And the symptoms are still there

From Guest

The test showed me the correct (positive) result only at 6 weeks of pregnancy. so I don’t know who shows it on the 10th day after PA...

From Guest

It feels like everyone here is so happy about pregnancy.. But I just took the test with fear.. 10 days after the test, negative result.. I hope I didn’t lie!

From Guest

4 days before the delay it showed a weak 2 stripe, after another 2 days the stripe was even clearer. When you are waiting for such news, tests are a good thing, my mommy is happy and my future dad is calm.

To know how and when to take a test, you need to understand how it works. It is also important to know at what day of delay the test will accurately show pregnancy?

The number of strips that will be determined after its use depends on the amount of hCG hormone produced in the female body. Unofficially, it is called the main hormone of pregnancy, because it begins to be produced precisely after attachment. ovum. The hCG hormone is found in fluids such as blood and urine. The test uses special reagents that are sensitive to hCG, and if the amount of it in the urine is large, then two stripes are detected. When there is no pregnancy, it will show one line. The problem is that all women expecting a baby have different levels of hCG in their blood and urine before birth. The drug may simply not recognize a unique condition. That is why it is important to know at what day of delay the test will show pregnancy exactly, how to count the weeks after fertilization and to know at what week ovulation occurred in the body.

It is worth knowing that the amount of hCG increases day by day after fertilization and decreases some time before birth. Therefore, the later you decide to do the test, the more likely it is that it will show the correct result exactly, and you will see two stripes.

However, when it comes to pregnancy, and you want to find out your condition as quickly as possible, it is very important to understand from what day of delay the test accurately shows pregnancy.

With a regular cycle, it is easier for a woman to determine pregnancy. If we take for example a cycle of 30 days from the last menstruation, then ovulation will occur on the 15th day. The egg is capable of fertilization for two days. After this, it moves to the uterus for about five days and attaches to it. In other words, a pregnancy test will reveal a special condition on the 26th day of the cycle. But you can find out about your condition by a blood test, which can most accurately show an increase in hCG, a little earlier - on day 22. But how accurately is pregnancy identification guaranteed? It depends on the amount of the hormone in the female body. If you do not want to wait for a delay from the moment of your last menstruation, you can use a highly sensitive test that can determine the condition several days before the expected onset of your next menstruation.

If you want to find out on what day of delay the test will accurately show pregnancy, then it should be carried out as late as possible. The accuracy of the result also depends on how sensitive the drug is to the hormone. If the test is highly sensitive, then two stripes will appear exactly on the day of the delay. However, if the test is of high quality, then it will be able to identify two stripes even before the delay appears.

The drug is able to accurately identify the week of pregnancy if the woman knows the time of ovulation and the day of her last menstruation. With a regular cycle, this is easier to find out, but if it is not regular, you can help determine when the egg left the ovary using special ovulation tests and how your body temperature rises. When the date of ovulation is clear, you can accurately determine the day of fertilization by adding 15 days to the date. At what day of delay will the test show pregnancy? Usually he determines this already on the fifth day with extreme accuracy.

Test: how to do it correctly?

Very often, women rush to determine pregnancy from the very first week of delay from the day of their last menstruation, without even thinking about how to do the test correctly. It is believed that everything is simple: open it, place it under a stream of urine and get the result. But even the instructions for it indicate that if it is used incorrectly, it is definitely impossible to get ahead of the state of pregnancy.

The best time to take the test is early in the morning. It is in the morning that the hormone in the urine is highest. Although the most modern and expensive tests show the result accurately at any hour of the day. If you want to do the test during the day, the urine should be more concentrated. That is, it is necessary to reduce the amount of fluid consumed. However, you can do it a week after the delay from the last menstruation both during the day and in the evening, because the amount of the hormone that is concentrated in the urine should be high.

What does it mean to take a pregnancy test correctly? This is discussed in detail in the instructions supplied with it. There are some rules that are not specified in the instructions, but they must also be followed.

Firstly, you should open the drug before you are going to do the test. Secondly, before purchasing, be sure to look at the integrity of the packaging. If it is broken, it is better not to do the test. In some cases, when unpacking it, one stripe is clearly visible on it. It is better not to use such a drug, since, most likely, the storage conditions were violated. Third, if you are going to use a urine collection container, it must be sterile.

What tests are there?

The result depends not only on the level of hCG in your urine, but also on how sensitive the drug is to this hormone. There are currently four types of tests that can help you determine the condition.

The most popular are still strip tests. These include Evitest and Frautest, quite famous among women, of German origin. These options have proven themselves well, since the manufacturer uses high-quality reagents. If you choose a cheap option, the result may be questionable, since cheap reagents are used in the production of an inexpensive product.

Strip tests are quite easy to use, but not always convenient. It is better for them to purchase a sterile container in which the urine will be collected. Then the drug should be lowered into it to a certain level and held for about five seconds. The result is determined after three minutes. Moreover, the time of appearance of the second stripe depends on the level of the hormone in the urine. The lower it is, the slower the band will appear. The manufacturer also often indicates that the result can be considered reliable if more than 15 minutes have passed. That is, if the second line appeared only after a quarter of an hour, then you should not trust the result. It is important to keep in mind that even a very pale second line indicates that you are about to give birth soon.

On what day will the drug show results exactly? You can use strip tests even before the delay from your last menstruation, but it is better to do this from the first day.

Tablet options come in a special box with holes. A small amount of urine - about four drops - is placed in one hole, and the result appears in the other. Two stripes may appear after a minute, or may appear only after ten. At what day of delay will the test show pregnancy? The tablet version can also detect pregnancy from the very beginning of the delay after the last menstruation, but it is not very convenient.

The inkjet option is much more convenient in this regard. It is very easy to do: just place the tip of the dough under the stream of urine, but you can do this as usual, after first collecting the liquid in a container.

The advantages of the inkjet version are its high sensitivity. But how accurately does it guarantee the correct result, and for what day of delay can it show two bands? Usually it shows pregnancy a week before the expected menstruation.

The most modern are electronic, or digital, options. To make it, you need to place the tip of the test in the urine and wait three minutes. IN in this case a positive result is determined not using traditional stripes, but using the “+” sign or the word “pregnancy”, which means “pregnancy”.

It is the most accurate option that can clearly show pregnancy a week before the missed period after the last menstruation. An electronic pregnancy test is also the most sensitive of all of the above. It shows the correct result a week before your expected period, so buy it. The electronic version will help you understand more accurately. The downside, besides the high cost, is that the inscription indicating that the woman is about to give birth will disappear over time and will not leave a memory of such an important event.

• Some electronic tests also determine the exact week of pregnancy, which will help you find out your due date.

When is the test negative?

A negative result does not always mean that conception has not occurred. There are many cases where the test stubbornly could not detect two bands, but after nine months the woman eventually gave birth. Therefore, if all the signs of an interesting condition are on your face, but during the check only one line appears, then you should consult a doctor.

Why can the test show one line when in fact the body is preparing to give birth? This situation may be caused by illness. For example, if a woman has endocrine system dysfunction. The test will be negative if the mother's body is about to reject the embryo, in other words, a miscarriage is about to occur during the initial weeks.

In the first two weeks after the delay from the last menstruation, for some representatives of the fair sex, the level of a special hormone in the urine still remains low.

One band can be determined if there are diseases of the heart or genitourinary system. If a woman suffered from pyelonephritis several weeks ago, then the drug may well show only one strip instead of two, even if the delay is already more than a week.

There is no pregnancy, but the test shows two lines

This is also a very common situation. When a woman sees two lines on the test, she is already preparing to give birth to a child, but later it turns out that the result was false positive.

The first reason is dysfunction of the female genital organs, namely the ovaries, or the occurrence of a tumor that can produce hormones. The second reason is a low-quality test, the expiration date of which has long passed. Also, two stripes can be detected if a woman has recently given birth, and only two months have passed since the birth.

Pregnancy and pathologies: what will the test show?

An ectopic pregnancy is a serious threat to a woman’s life, since in this case the fertilized egg is not attached to the uterus, but begins to develop, for example, in fallopian tube. As the embryo develops, it can burst, which often leads to death. What to do in this situation? The problem is that a woman will not be able to detect such a pregnancy on her own. The test will indicate a positive result, because the body will still begin to produce the hCG hormone. But in this case, the second band will be barely noticeable, since the hormone will be produced in smaller quantities.

Obvious signs of pregnancy outside the uterus are bleeding and severe pain lower abdomen. If you have any suspicions, you should go to the hospital immediately.

A frozen pregnancy is a very unpleasant and sad event when the embryo stops developing and dies inside the womb. It is impossible to identify it 100% on your own, but it can still be identified by some signs. Firstly, during a frozen pregnancy, all signs such as nausea or breast tenderness suddenly disappear.

Secondly, if clear stripes appeared at first, then over time the second stripe may disappear. If there is a suspicion of a frozen pregnancy, the test should be repeated.

Doubts often grip women if they really want to give birth, but when determining the condition, the second line will be barely noticeable. A questionable result may indicate that the result is positive, but to confirm it you should wait a little, at least a week. Then the hormone level will increase, and it will be possible to take a pregnancy test with greater confidence that the result will be positive.

But sometimes a woman convinces herself that she sees a second stripe. The places where stripes should appear if the result is positive are always marked on the preparation. Therefore, if in any doubt, you should purchase a more expensive option and check the readings again.

It doesn’t matter at all from what day of delay the test usually shows pregnancy, since each body is individual. Sometimes the incorrect result lasts more than three weeks after the delay, but it can last for months. Therefore, at the first signs, you should visit a medical office, where the doctor is more likely to tell you whether you are preparing to give birth or not during the first weeks after the delay.

The doctor will be able to determine pregnancy by the condition of the uterus, which swells slightly and changes color, as well as by a blood test for hCG, which will show the result in the first days of the delay much more reliably than conducting home tests. He will tell you how long you have left before giving birth.

When should you prepare to give birth?

Several decades ago, a doctor could determine the date of birth by the movement of the fetus. Now there are other methods.

If you have two stripes and you are preparing to give birth, you need to know how much time is left until delivery. A doctor will help you do this, but you can try to determine this yourself.

The date of ovulation will help you find out how much time is left before giving birth. You should determine this day and add another 280 days to it. If you cannot determine the date of ovulation, you should calculate the date of birth at the middle of the last menstrual period.

If you cannot determine the date of birth on your own, then doctors will help you do this. Based on the size of your uterus and an ultrasound, they will be able to determine the exact date when you are due to give birth.

Women who have been planning a pregnancy for a long time know how difficult it can be to guess the “right” day to conceive. But it can be even more difficult to wait until the delay begins. You can do the test earlier, but the accuracy of its readings will not be high. To save money and nerves, you need to learn how to correctly count the days from probable conception in order to know when to start self-diagnosis.

When do tests become positive?

The test will show you the long-awaited second strip only after the concentration of the hCG hormone in the urine increases. It is with this that the reagent applied to the test of any modification and cost reacts. The reagent contains special antibodies to molecules of a hormonal substance, and if the number of molecules in the urine is sufficient for complete chemical reaction, a second stripe will appear in the test zone.

The hormone is produced by thin villi on the outer part of the fertilized egg - the chorion. Human chorionic hormone begins to be produced only after the embryo implants in the uterine cavity, and this event usually occurs a week after conception.

There is also an earlier implantation, but not earlier than 5 days after conception; there is also a later implantation of the embryo, but no later than 9 days after conception. The hormone level doubles every 2 days.

And first of all, its concentration increases in the blood plasma, and only then, when excreted by the kidneys, the molecules of the substance necessary for diagnosis begin to penetrate into the urine. Usually the most early , in which the most sensitive tests can detect the presence of the hormone and show a second, even weak, strip is considered 9-11 days after conception.

That is, theoretically, if both ovulation and implantation happened on time, 4 days before the expected menstruation, sensitive tests can give a positive result. But from the first day of the delay, in almost all pregnant women the level of the hormone is high enough for home test diagnostic systems to successfully cope with the task of determining it.

Starting point - where to start? Understanding when a test will show pregnancy is not enough. You need to know exactly where to start counting the days until testing. Many people believe that you need to count from the moment of conception. The difficulty is that a woman cannot determine the moment of fertilization. Sexual intercourse could have occurred before ovulation; sperm live up to 3-5 days

, and it is one of them that can fertilize the egg after it leaves the follicle on the day of ovulation.

But this may not happen, and then other sperm from the “fresh” batch will have a chance if sexual intercourse is carried out before the female reproductive cell dies. She lives on average about one and a half days. And it is precisely this time that is always the time of conception, whenever sexual intercourse occurs - before or during the ovulation period. Therefore, it is better to count the days from ovulation.

During the first 3 days after conception, the embryo moves through the oviduct into the uterine cavity. On the 4th day after conception, it is already in place, but several more days may pass before implantation. As long as implantation has not completed the successful attachment of the embryo, no changes occur in the hormonal background that may indicate pregnancy. Only from the moment the chorionic villi are reunited with the maternal blood vessels does the woman’s body receive a signal about the need to start working in a new mode, in which all organs and systems will begin to adapt to bearing offspring.

This means that from the first day after conception or after ovulation there is no point in doing any tests. Only the 7th day after conception does something begin to change, but this amount of hormone is still not enough to color the second line on the test. The earliest implantation is possible from the 5th day, and the latest - on the 9th day.

According to statistics, only about a third of women with increased individual sensitivity of the nervous system can feel implantation.

The rest remain in the dark. Indirect signs include the appearance of weakness, a metallic taste in the mouth, unusual pink or brownish discharge on the 6-7th day after conception. If you notice such symptoms, after 3 days you can try to do the first test.

But note that a small amount of the hormone requires a high threshold for the perception of the reagent. Therefore, only ultrasensitive diagnostic systems are suitable for the earliest diagnosis. Their packages, regardless of name and price, are marked with 5-15 mIU/ml. Tests with standard sensitivity are unlikely to show a second line before the delay begins.

Possible situations Sometimes women are delighted to note that tests show a weak second line already 5 days before the delay begins. This suggests that implantation was earlier or ovulation occurred earlier than expected.

This is quite possible, especially if a woman is young, active, travels, changes time and climate zones. With severe stress, slight shifts in ovulation are also likely. In this case, the amount of hormone will be higher before the delay occurs. But it may also turn out that the delay has already begun, and the tests are still negative . It could be a sign of late implantation or late ovulation. Ovulation may shift even by a few days due to hormonal imbalances, stress, or taking oral contraceptives in previous periods.. Lack of sleep, working at night - all this also leads to cycle instability.

Implantation occurs later when the level of progesterone in a woman’s body is insufficient, when the endometrium is thin, which happens after several previous abortions, several births before the current pregnancy, or diagnostic curettage of the uterine cavity.

Therefore, you should not rush to conclusions if on the 10th day after conception the test does not show you a second line. If pregnancy has occurred, then after a few days the concentration of human chorionic gonadotropin will increase; it is enough to just repeat the test after 2-3 days. If a second faint line appears, this may be a sign of a low amount of hCG. Soon he will grow up, the stripe will become brighter.

If days go by and a weakly positive result persists, you should consult a doctor - it is possible ectopic pregnancy, with it the level of hCG is always below normal, and the increase is slow.
