Pregnancy can be detected when menstruation is delayed a few days

Pregnancy is usually detected more than 7 days after menstruation. After pregnancy, the level of human chorionic gonadotropin (HCG) in the body will gradually increase. HCG is an important indicator for detecting pregnancy. When menstruation is delayed for about 7 days, HCG content in urine or blood usually has reached a level that can be detected. Pregnancy can be determined initially by testing urine or blood HCG levels with early pregnancy test strips. However, everyone's menstrual cycle and ovulation time are not exactly the same. Some women may ovulate later, so pregnancy will be delayed accordingly, and it may take longer to accurately detect pregnancy. Therefore, if the test is negative after 7 days of menstrual delay, it cannot completely rule out the possibility of pregnancy. The accuracy of the test method will also affect the results. Although the test paper is convenient, there may be some errors. If there are doubts about the test results, it is recommended to go to the hospital for blood HCG testing, which is relatively more accurate. In addition to detecting pregnancy, there may be other reasons for delayed menstruation, such as endocrine disorders, excessive mental stress, excessive dieting, certain diseases, etc. Therefore, it is not possible to determine pregnancy solely by delaying menstruation. It is necessary to combine the test results with other physical symptoms for comprehensive judgment. If pregnancy is confirmed after multiple tests or hospital examinations, pregnancy care should be carried out in time, and regular check-ups should be carried out according to medical advice to ensure the health of pregnant women and fetuses. At the same time, it is also very important to maintain good living habits and mentality.
