The longer the time after the couple's sexual life, the more accurate it is. In short, you can test whether you are pregnant within one week after having sex, or about three weeks at the latest. Let me give you a detailed introduction below.

Pregnancy test strips: Initially, it can be detected 7 days after the sperm and egg combine.

The principle of early pregnancy test is to test the hCG value, that is, the value of hCG gonadotropin in the body. This hormone will be metabolized into the urine through the blood circulation system of pregnant women. Early pregnancy test strip pregnancy test is a relatively convenient and quick way to detect early pregnancy. This type of hormone is produced by the embryo and usually appears in the urine a few days after pregnancy. However, due to the small amount, it is not easy to test it at the beginning, and it will become increasingly obvious from 10 to 14 days. Going to the hospital for a blood test can also measure the hCG value, which is more accurate.

It should be noted that although many pregnancy test strips indicate that women can take a pregnancy test one day after missing their normal menstrual period, in fact, not all pregnant women secrete the same rate and amount of hCG hormone, which varies from person to person. If you have to do a urine test, a negative result may be incorrect.

Early pregnancy test strips and pregnancy test sticks are only the first step in pregnancy screening and cannot be used as a diagnostic method. In order to prevent ectopic pregnancy and ensure the healthy growth of the fetus, further examination is required in the hospital.
