The HCG value is the value of human chorionic gonadotropin, which is usually tested when you are first pregnant, and is released into the bloodstream after the formation of a fertilized egg, so a blood test can effectively determine if you are pregnant. If you want to determine whether you are pregnant or not, you can go for an HCG test at 10 days after intercourse, and if the value is more than 25 nmol/L, you can determine that you are pregnant. The value of HCG increases faster until the second month of pregnancy, and then decreases until the middle of pregnancy. If you want to know whether you are pregnant or not, you can go to a regular hospital and get tested in this way.
