After how many days to do a pregnancy test to get a reliable result? Read on in the article.

In anticipation of a successful conception, many of us go to the pharmacy the next day after an intimate night with a partner, but after how many days do a pregnancy test to get a reliable result? With this question we will try to understand, having considered various situations.

During pregnancy, the female body begins the active production of a special hormone, abbreviated to HCG. It is his and seek out all the rapid tests.

Play hormone

During pregnancy, the female body begins the active production of a special hormone, abbreviated to HCG. In the minimum amount, this hormone is found in any organism, both in women and men. However, its amount can be detected only with the help of special clinical blood tests in laboratories.

If the conception of a child has occurred, the level of hCG increases significantly and continues to increase with pregnancy, preventing ovulation, as well as ensuring the growth and development of the crumbs. In this case, to determine the high content of the hormone can be already in the study of urine. And to do it at home is easy. It is only necessary to strictly follow the rules of the test. And the main one is the amount of time elapsed after unprotected intercourse.

Before the amount of hormone in a woman's body reaches the desired level, it will take some time. That is why the rush during the study will be unnecessary.

When to do a test

As we found out, the hormone hCG acts as a reagent for the manifestation of the long-awaited two strips. However, before the amount of hormone in a woman's body reaches the desired level, it will take some time. That is why the rush during the study will be unnecessary. After all, if the level of hCG in the urine is low, you risk getting a false negative result.

The greatest chance of conceiving a child occurs during the period of ovulation in a woman, as well as the day before and after her. If during this period you had unsafe sex, then it makes sense to conduct a pregnancy test. However, this should be done no sooner than after 14 days (when using rapid tests of high sensitivity for at least 10 days). With the average duration of a regular cycle of 28 days, after these two weeks, many women mark the delay of menstruation.

This is due to the fact that a day after the fertilized egg is attached in the uterus, the level of hCG is still too low for identification. A strengthened hormone production begins to be carried out at least a week after implantation.

More or less reliable results can be obtained on the 14th day after ovulation

Tip! It is better to wait a little with the diagnosis of pregnancy, and not to upset yourself ahead of time with an erroneous negative result.

Tests of different sensitivity: determine pregnancy before the delay of menstruation

The minimum level of hCG, which is contained in the urine at the time of diagnosis, should be 10 mMe / ml. However, in pharmacies most often we get test strips, the sensitivity of which is 20-25 mMe / ml. And this hormone concentration is reached only in 2-2.5 weeks after successful conception.

So with a regular four-week menstrual cycle, a pregnancy test is best done for 3-5 days delay. An earlier diagnosis before the expected menstruation or in its absence on the first day most often shows a false-negative result in 85% of cases.

With a regular four-week menstrual cycle, it is best to conduct a pregnancy test for 3-5 days delay.

If you want to make a rapid pregnancy test before the start of your period, you need to purchase super sensitive strips at the pharmacy. Usually they detect pregnancy at 7 days with a sensitivity of 10 mMe / ml and 10 days at 15 mMe / ml. To confirm pregnancy before the delay of menstruation, these types are suitable only.

Pregnancy test with irregular cycle

If you are a "lucky person" with an irregular menstrual cycle, then you may have a problem with the timing of the diagnosis of pregnancy with the help of express strips. With this schedule it is extremely difficult to determine the day of ovulation and favorable days for conceiving a child. And if you are not under the supervision of a specialist and do not conduct special tests for ovulation, then understand exactly when the next menstruation should come. In the same way, as well as in time to find out a monthly delay.

Tip! In general, a more or less reliable result of a pregnancy test can be obtained 17-18 days after unprotected intercourse.

It is advisable to diagnose and at the first signs of pregnancy (except for delayed menstruation).

With an irregular schedule it is extremely difficult to independently determine the day of ovulation and favorable days for conceiving a child.

In this case, the presence of a barely noticeable second strip is already a reason for consulting a gynecologist to confirm pregnancy and exclude possible pathologies.

Breastfeeding tests

To determine pregnancy during lactation is a very difficult task. The first time you will have no menstruation (approximately from 6 months to one and a half years). Some women claim that breastfeeding prevents unwanted pregnancies. In fact, this is one of the most common erroneous opinions. After all, the absence of menstruation does not indicate the absence of ovulation itself. So pregnancy can occur already after one estimated menstrual cycle. And very often, women miss this moment, taking the absence of menstruation, for granted.

If you want to play it safe or just do not plan to give birth to babies of the same age, it is recommended to carry out an express diagnosis of pregnancy during lactation every month until normalization of the menstrual cycle. As soon as the monthly period begins again, and the schedule becomes regular, it is necessary to do a test for determining pregnancy after an intimate relationship as usual - after a few days of delay.

Artificial insemination and injections of the hormone HCG

With artificial insemination, the process of sperm entering the uterine cavity is different from the usual sexual intercourse. To do this, the day is exactly selected in accordance with the menstrual schedule and periods of ovulation. But otherwise, the process of fertilization of the egg and the attachment of the ovum into the uterine cavity is carried out in the same way as with natural conception.

So a pregnancy test after the procedure is carried out after 17-18 days, that is, approximately on day 3 of the delay of menstruation with an average cycle of 28 days.

In the case when stimulation was carried out with the help of hCG injections, there is no point in checking the occurrence of the pregnancy immediately after completing the course of procedures. The concentration of hormone in the blood and urine will be so high that any, even the weakest test will show the onset of pregnancy. To be sure that the two desired strips do not deceive your maternal hopes, after a course of hCG injections, you should do the test in 15-17 days.

In Vitro Fertilization and Pregnancy Test Results

In vitro fertilization for most couples who are already desperate to have a baby is often the last hope. After the IVF procedure, a pregnancy test can be done two weeks after the replanting of the fertilized egg. Do not once again run to the pharmacy and experience feelings about the lack of a positive result ahead of time. To successfully attach the embryo in the uterine cavity, you need peace and comfort. So be patient and wait for the proper time.

And even if after 14 days a pregnancy test shows a negative result, this still does not indicate the absence of pregnancy. Perhaps the concentration of hCG in the urine is still not high enough. Just repeat the test a few days later or donate blood for analysis in the clinic where the IVF procedures were performed.

After the IVF procedure, you can do a pregnancy test two weeks after the replanting of a fertilized egg.

Test after abortion, abortion

Usually, a woman buys a pregnancy test after an abortion to verify the quality of the procedure. If for some reason you cannot be 100% sure that all fetal membranes were removed from the uterus during an abortion, ordinary test strips are unlikely to help you with this.

  • First, the level of hCG will still be high for some time after the procedure. Still, your body needs to recover.
  • Secondly, it is possible to detect the presence of possible complications and pathologies only during the examination at the gynecologist and by ultrasound.

In general, reliable results of a pregnancy test after an abortion can be obtained 2-3 weeks after the procedure. By this time, the hormonal background of the woman is normalized, and the level of hCG is reduced to the desired level.

Reliable results of a pregnancy test after an abortion can be obtained 2-3 weeks after the procedure.

What time of day to analyze

Regardless of the causes and method of conception, a pregnancy test should be done in the morning immediately after sleep. The longer you did not go to the toilet, the higher the concentration of hCG in the urine at the time of the test and, accordingly, the more reliable the result.

Manufacturers of modern tests of high sensitivity claim that with their use the procedure can be carried out at any time of the day. But it is better to determine early pregnancy in the morning or at least 4-5 hours after the last urination.

Important! Diuretic drugs, beverages and foods contribute to frequent urination and lower levels of hCG.

But if we are talking about a long delay (5 days or more), any time of day is suitable for conducting the test. The concentration of the hormone at this time is already high enough to determine the onset of pregnancy using a test of any sensitivity.

Regardless of the causes and method of conception, a pregnancy test should be done in the morning immediately after sleep.

Finally, I would also like to note that all the above norms and terms are conditional, and it is not necessary to calculate the appropriate time for the test with an accuracy of up to an hour. And the point is not that the body of each woman is individual. After all, there are so many factors affecting fertilization. This may be a shift in the ovulation date due to stress or physical exertion, and a change in the cycle, and even a longer “journey” of an already fertilized egg to the uterus.

All this has a significant impact on the production of the hormone hCG. And although modern manufacturers of test strips insist on the reliability of the results, you should not believe them unconditionally. Previously, the test in almost every other case gives a false-negative result. And even if on the third day of the delay your long-awaited two strips have not yet appeared, just wait a little longer and repeat the procedure in a few days.
