Many women who dream of knowing the joy of motherhood are interested in how quickly the test will show pregnancy after unprotected intimacy? Pregnancy tests are based on the sensitivity to increase in the urine of the hormone of chorionic gonadotropin (in-hCG). The level of HCG in the blood of a non-pregnant woman varies between 0-5 mMe / ml, the indicator above this value the pregnancy test recognizes. We will try to answer the question, at what time period the pregnancy test shows a positive result, and also explain with what it is connected.
How much does the test show pregnancy?
With a normally developing pregnancy, the test will show a 100% reliable result on the seventh day after the delay in menstruation. There are pregnancy tests for hypersensitivity, which can confirm that a woman will soon become a mother, on the first day of a delay in menstruation. It's about the so-called inkjet tests, for which you do not need to collect morning urine. It is enough to put it under the jet of urine, at the same time it can be done at any time of the day.
So, what is the gestation period for this test? If you believe the instructions, a positive result with this test can be obtained already with an increase in chorionic gonadotropin in the blood up to 10 mM / ml, which can correspond to 5 to 7 days after the occurred conception.
I would also like to say about the multiple pregnancy , in which the increase in the level of chorionic gonadotropin occurs two times faster than in pregnancy by a single fetus. In such cases, even before the delay in menstruation, the test will show pregnancy.
Thus, having become acquainted with the peculiarities of the detection of elevated chorionic gonadotropin, we saw that the seventh day is the time when the test will accurately show the pregnancy. A more reliable study confirming the onset of pregnancy is a blood test for determining the level of chorionic gonadotropin in dynamics.
Does the test always show pregnancy?
Now let's talk about false positive and false negative results of the pregnancy test. So, the test does not show pregnancy for a long time (false-negative result), if:
- the test is used too early;
- expiration date of the pregnancy test;
- development of an ectopic pregnancy is possible;
- the test is not done correctly (to avoid this, you should carefully read the instructions and follow it);
- if the day before the woman drank too much liquid, and the concentration in the blood of the chorionic gonadotropin decreased.
There are several reasons why a test can show a pregnancy even when it is not, they are referred to as:
- Malignant tumors that are capable of producing chorionic gonadotropin;
- reception of drugs from infertility, which contain chorionic gonadotropin;
- finding in the uterine cavity the remains of the fetal egg after spontaneous or medical
(medical or instrumental) abortion.
In all these cases, even with a monthly test, pregnancy can be indicated.
With the onset of a delay in menstruation and confirmation of the desired pregnancy with a positive test, do not relax. It is necessary to address to the gynecologist in female consultation that it has confirmed normally developing pregnancy. To do this, he must conduct a gynecological examination and confirm that the enlarged uterus corresponds to the expected duration of pregnancy. And also to appoint a number of laboratory and ultrasound studies.
