How many days of pregnancy can be detected?

Generally, only a few people can detect the pregnancy within 10 days, while it is difficult for most people to detect it. This is related to the principle of early pregnancy test strips. The detection principle is that after the sperm and egg combine to form a fertilized egg, it takes 6 to 8 days for the endometrium to implant, and 7 to 10 days for the HCG secreted by the placenta to enter the urine. However, due to the small amount, it is difficult to measure it, and the measurement at this time is extremely inaccurate (because most people will get a weak positive at this time, and a weak positive may also be caused by impurities in the urine). Most measurements make it difficult to determine whether you are pregnant or not. Using early pregnancy test strips, the earliest it can be detected after intercourse is 7 days, usually 18 days, and in some cases it may take more than 20 days to be detected. 7 to 10 days after menstruation is to make the test results more accurate. The best time to test is 18 days after intercourse, or 7 to 10 days after the next menstruation.

When testing in the hospital, the blood HCG test method is generally used. Eight to ten days after sexual intercourse, you can have a blood test for HCG to determine whether you are pregnant. This is currently the earliest and most accurate way to test. After a pregnant woman becomes pregnant, HCG will appear in both her urine and blood. The accuracy of blood HCG testing is over 99%, and the measurement time can be appropriately advanced. In addition, blood HCG can also detect abnormalities such as ectopic pregnancy, multiple births, and abnormal embryonic development. However, if you use urine pregnancy test, gynecological examination, B-ultrasound examination and other methods, the time of detection can be the same as that of early pregnancy test paper, or even later.

Through the above introduction, we have a good understanding of how many days it takes to detect pregnancy. Therefore, when women want to get pregnant, they should pay attention to their own situation. After a woman becomes pregnant, her body will undergo obvious changes, so at this time, women also have great changes in diet and emotions.
