Pregnancy test sticks are used for a few days after menstruation

Pregnancy test is usually used 7 days or more after menstruation is delayed.

After pregnancy, HCG (human chorionic gonadotropin) levels will gradually increase, but it takes a certain amount of time to accumulate in the urine can be detected. In general, 7 days after menstruation, HCG levels in urine are relatively high, when using pregnancy test can improve the accuracy of the test.

If you use pregnancy test too early, false negative results may occur. If you test just one or two days after menstruation, it is likely that HCG levels are too low to detect, resulting in misdiagnosis as not pregnant.

However, everyone's menstrual cycle and ovulation time are not exactly the same. Some women may ovulate later, and the pregnancy time will be delayed accordingly.

To ensure the accuracy of the results, you can test several times. For example, repeat the test every few days, or combine it with other tests such as HCG testing in the blood to make a comprehensive judgment.
