How long after cohabitation can we test for pregnancy? When is the most accurate pregnancy test result

If a man ejaculates after a woman is in the same room, the sperm can only enter the female fallopian tube 24 hours later, and combine with the eggs discharged by the woman in the fallopian tube to form a zygote. The zygote, driven by the cilia in the fallopian tube, reaches the uterus after about 6-7 days.

At this point, women want to know if the answer to how long pregnancy can be measured is clear, but if women want to know the accurate results, it takes about 8 days from sexual intercourse to pregnancy. After 3 days of pregnancy, the woman's body or urine will undergo some changes, which can be accurately measured at this time. Generally speaking, 11 days after cohabitation.

Pregnancy test precautions

Pregnant women using test strips should be tested in the morning and during their first urination, as the results will be more accurate. However, women who have been pregnant for some time can choose any time period. Because there were significant changes in urine at that time, urine can be tested at any time.

When is the most accurate pregnancy test result?

Pregnancy papers can be tested 7-10 days after sexual intercourse, but the longer the time, the more accurate it is. The working principle of early pregnancy test strip self check is to detect the HCG value, which is the value of human chorionic gonadotropin. This hormone is made from the placenta and usually appears in urine after a few days of pregnancy, but due to its small amount, it is not easy to test at the beginning until it becomes more pronounced 10 to 14 days later.

Although many early pregnancy test strips indicate that women can undergo pregnancy self examination after missing their normal period for one day, in reality, not all pregnant women emit HHCG hormone at the same rate and amount, which varies from person to person. Experts point out that urine testing is too early and negative reactions may be incorrect. It is best to undergo a pregnancy self check after two weeks of late menstruation, as the results will be more reliable.

When it comes to early pregnancy test strips, married women have heard of them. However, many women do not know how long the early pregnancy test strip can test. If tested too early, it may not be pregnant yet, and the conclusion is naturally inaccurate. Therefore, it is important to grasp the testing time.

Test methods for early pregnancy test strips

The accuracy of early pregnancy test strips. If you do pregnancy self testing at home without any external guidance, the general test results can only reach 500% to 90% accuracy. If pregnancy testing is conducted under the guidance of a doctor, women can use the test paper correctly according to the instructions, and the testing accuracy may be close to 100%.

The method of using early pregnancy test strips requires complete reading of the instructions before testing, and the reagents and urine samples must be restored to room temperature (20) ℃ -30 ℃). Remove the reagent strip from the original packaging aluminum foil bag and use it as soon as possible within 1 hour. Insert the reagent strip into the urine sample in the direction of the arrow. Wait for the appearance of the purple strip, and the test results should be within 3 minutes. After 10 minutes, it is deemed invalid.
