How many days after sex can you detect pregnancy

Various pregnancy test methods are based on the induction of certain elements in the female body, and then display the test results in an obvious way. For example, HCG refers to hcg gonadotropin. It will double in volume after pregnancy and will be zero if you are not pregnant. Therefore, it is very accurate to determine the number of weeks of pregnancy based on HCG, and HCG should be checked during early pregnancy. The earliest time for the combination of sperm and egg to produce HCG is about 6 or 7 days after embryo implantation, and it takes about 11 days for the fertilized egg to complete embryo implantation. Therefore, the first pregnancy test can be done around 6 days, but if you want a more accurate result, it is best to wait until 11 days. In terms of testing time, the results of experiments performed in the morning and at night may be different. Generally, the HCG value in morning urine is the highest, so morning urine is usually chosen for urine testing.

Of course, the testing also depends on the person. Under normal circumstances, the longer the pregnancy is, the more accurate the test results will be. This is because the principle of the early pregnancy test strip is to detect the hormone hcg produced by the embryo, which usually appears in the urine during pregnancy. Because the amount of hcg in the early stages of pregnancy is small and may not be detected, it will not become obvious until the menstruation is delayed for more than a week. Therefore, if you want to improve the accuracy of the pregnancy test, you can wait 10 days after the menstruation is delayed before testing for pregnancy. However, the results of self-test pregnancy may also be biased. Therefore, in order to avoid this situation, you can consider going to the hospital for an early pregnancy test about 10 days after your period is delayed. In addition, it should be noted that not everyone can be tested for pregnancy after 10 days of delayed menstruation. Because some people may be able to detect pregnancy after 20 days of pregnancy, but for others it may take 40 days or longer.

Different ways to test for pregnancy

There are many changes in a woman's body during pregnancy, so there are also many ways to test for pregnancy. Moreover, the human body undergoes different changes at different stages, so there are appropriate times for each pregnancy test method. If you use a pregnancy test stick to detect pregnancy, you can choose to test it 3 to 5 days after your period is delayed. If after the test, you find that there are two red bars on the test paper, it means there is a high possibility that you are pregnant. If there is only one bar, it means you are not pregnant.

If you feel that methods such as pregnancy test sticks may be inaccurate, you can choose a more accurate method such as B-ultrasound. You also need to wait about 7 days in Yunjing before going to the hospital for a B-ultrasound examination.
