How many days after sex can I use a pregnancy test stick to detect pregnancy

For couples who really want a baby, they will not ignore any sign of pregnancy. In fact, if you want to know whether you are pregnant, you can use a pregnancy test. So how long does it take to test the pregnancy? Today we will share some knowledge about this for everyone.

How long does it take to detect pregnancy?

Generally speaking, you can test yourself 7-10 days after having sex. You can test pregnancy by testing morning urine with a pregnancy test strip or pregnancy test stick. The longer the time after sexual intercourse, the more accurate the test will be. In short, you can test whether you are pregnant within one week after having sex, or about three weeks at the latest.

Generally speaking, in the early stages of pregnancy, women will experience a series of early pregnancy reactions such as dizziness, nausea, sleepiness, breast tenderness, etc. These reactions usually become more obvious 10-14 days after pregnancy and disappear on their own after three months. Therefore, if a woman has the above symptoms, she can use pregnancy test strips and pregnancy test sticks to test for pregnancy.

The principle of pregnancy test is to test the hCG value, that is, the value of human chorionic gonadotropin. This hormone will be metabolized into urine through the blood circulation system of pregnant women. Pregnancy test strips are a relatively convenient and easy 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 difficult to test it at the beginning. It will not become obvious until 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 do a urine test too early, a negative result may be incorrect.

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.
