Pregnancy test: when, after how much and how many times do you need to do a pregnancy test

These miniature diagnostic systems for home use are accessible and convenient, and any woman of childbearing age, sexually active, should be able to use them.

When do you need to take a pregnancy test?

The first question that arises when you suspect a possible conception is when you need to do a pregnancy test, how long should you wait?

Modern pregnancy tests are very sensitive and are able to determine pregnancy as soon as possible, sometimes even before the delay of menstruation.

But it is worth remembering that the tests are not almighty and will not show the pregnancy the next day after the “dangerous” sexual relationship. This is due to the peculiarities of the conception process and the mechanisms of the tests.

The beginning of the test.

To understand how much you need to do a pregnancy test, it is important to remember that ovulation occurs approximately in the middle of the cycle, and conception occurs a few days after the release of the ovum.

At the same time, after the ovum has been fertilized, there is a gradual gradual increase in the blood level of the hormone hcch.

As its concentration increases, at the time of implantation of a fertilized ovum in the wall of the uterus, approximately 7 to 10 days, the level of hcch increases in the urine. At the same time, the hgch level doubles approximately every 24 hours.

A pregnancy test is usually recommended on the first day of menstruation. In general, tests with a sensitivity of 20-25 mm / ml (paper strips) show pregnancy in this situation.

There are more sensitive tests that can show the presence of pregnancy several days before the delay (generally no more than 2-3 days), they have a sensitivity of 5 to 10 m / ml and, in general, they are jet tests

However, it is always worth remembering that in women with an unstable cycle, ovulation can be early or late, and conception can occur with a deviation from the average data. Therefore, to answer exactly how much you need to do a pregnancy test is difficult, wait for the delay of menstruation.

The instructions often indicate that the study should use morning urine immediately after waking up, but why should a pregnancy test be performed in the morning?

The fact is that the morning urine contains in the early stages the maximum amount of the hgch hormone and will show more accurate results than at other times of the day.

But if you use a test with high sensitivity, from 5 to 10 m / ml, the test time is not critical if there is a pregnancy and a delay, the test will show a positive result.

How to evaluate the result?

If you have performed a pregnancy test, it is important to evaluate the result correctly, especially if it is an early period, before the delay or your first few days.

If the test shows two strips, they are likely to be pregnant if there is unprotected sex in this menstrual cycle.

But it is worth remembering that hormonal changes, the presence of pathologies with the release of hgch hormone without pregnancy can affect the outcome. And if the test is done too early, even in the presence of pregnancy, it can show a lane.

And then the question arises: how many times do you need to do a pregnancy test? Generally, with a positive pregnancy test, one study is enough, the next step should be a visit to the doctor and an ultrasound.

If you have a delayed menstruation, while the pregnancy test is negative, do it again after a few days, maybe your sensitivity is not very good.

If the test was not positive after that, you should consult a doctor and find out the reasons for the delay sometimes, the tests are also incorrect.
