The common methods of eliminating pregnancy in clinical medicine currently include testing morning urine with early pregnancy test strips, blood tests for HCG components, B-ultrasound examinations, etc.

How to clear pregnancy after delayed menstruation

1. Early pregnancy test paper testing morning urine method: Because the female body will release human chorionic gonadotropin (HCG) after pregnancy, and this substance can be detected in the morning urine and blood in the early pregnancy period, female friends who want to rule out pregnancy in time due to delayed menstruation can first buy some early pregnancy test paper for morning urine test. It should be noted that it takes about seven to nine days for sperm and egg to combine and move into the uterus for the embryo to implant. Therefore, the result of testing with morning urine around 40 days of pregnancy, that is, seven days after menstruation, is most accurate. Before that, it may be tested negative or weakly positive. If the test result is negative, you can test again. If the test result is weakly positive, you need to see a doctor immediately.

2. Blood HCG test method: Detecting HCG components in the blood is one of the earliest ways to detect early pregnancy, and this type of test is relatively simple, requiring only a small amount of blood for testing. It is generally believed that women can do this test anytime and anywhere seven days after having sex, but the longer the menstruation is delayed, the more HCG content in the blood, and the more accurate the early pregnancy test results.

3. B-ultrasound examination: If a woman's menstruation is delayed for more than ten days, in other words, 40 days after menstruation, B-ultrasound examination can be used to rule out pregnancy. Most women can observe the gestational sac of embryo implantation in the uterus through B-ultrasound examination at this time. However, women who have sex late or have an ectopic pregnancy may not see the gestational sac in the uterus and need to continue the corresponding examination.
