Can I use test strips to find out how many days my period is late?

Menstruation is the most familiar physiological characteristic for our female friends. If the menstruation comes early, we will worry about irregular menstruation, and delayed menstruation is more troublesome, because for female friends who have sexual life, it means that they may be pregnant. If the menstruation is delayed, the easiest way to know whether you are pregnant is to use a test paper to detect it. So how many days of delayed menstruation can be used to detect it with the test paper is our most concerned issue.

Suggestions: 1. You can use an early pregnancy test strip to check 7 days after the menstrual cycle is delayed or 10 to 14 days after having sex. Two red lines on the test paper indicate a positive result, which means you are pregnant. In addition, you can go to the hospital for a blood HCG test 7 days after sexual intercourse. This is the most accurate way to check pregnancy.

2. If effective contraceptive measures are not taken during sexual intercourse and menstruation is delayed, the first thing to consider is the possibility of pregnancy. The self-test rate of the early pregnancy test paper is 75%. Relax and observe closely. If your period is delayed by 10 days, go to the hospital's gynecology department for a blood test or HCG or B-ultrasound examination to determine whether you are pregnant.

Tips: 1. When women do self-pregnancy tests at home without any external guidance, the test results can generally only reach an accuracy rate of 50% to 75%. After all, early pregnancy test strips have errors. If you suspect pregnancy, it is best to go to the hospital for a detailed examination, or you can get vaccinated as soon as possible.

2. If the Hcg concentration in the body does not reach a certain level, it may not be detected. This also depends on the hormone content and the sensitivity of the test strip. It can usually be detected in urine on the seventh day of a woman's pregnancy. And this kind of test paper still has a certain amount of false positives. You cannot just rely on a single pregnancy test to determine whether you are pregnant. The most reliable thing is to go to the hospital for a comprehensive examination in time, especially for those with weak positive results, so that measures can be taken as soon as possible.

For female friends who have sex, the biggest worry after not using any safety measures is when the test paper can be used to detect the delayed menstruation. However, the test papers on the market are not necessarily accurate, so it is generally recommended that our female friends go to the hospital for a detailed examination in time.
