Patient's question:
How many days after intercourse during ovulation should one wait before the earliest pregnancy test? First follow-up question: Can pregnancy be detected before the onset of menstruation?Doctor's answer:
??????Hello: You can test 7-10 days after intercourse, of course, the longer the time, the more accurate. The working principle of early pregnancy test strips for self-testing is to detect HCG levels, which is the level of human chorionic gonadotropin. This hormone is produced by the placenta and generally appears in the urine a few days after pregnancy, but because the amount is small, it is not easy to detect at first and becomes increasingly obvious only after 10 to 14 days. (HCG levels can also be measured through a blood test, and it is much more accurate). Although many early pregnancy test strips indicate that women can do pregnancy self-testing one day after missing their normal period, in fact, not all pregnant women release HCG hormone at the same speed and quantity, which varies from person to person. Gynecological and obstetric experts point out: "An early urine test may show a false negative result." Therefore, it is best to do pregnancy self-testing two weeks after the delayed menstrual period, so the result will be more reliable.
