Pregnancy can be quickly determined by a urine test or a blood test for human chorionic gonadotropin. Either pregnancy test is relatively quick and can produce results on the same day. Human chorionic gonadotropin is significantly elevated in the urine when you are pregnant, and you can take a urine test if your period is delayed for more than 10 days. Put a drop of morning urine on the urine drip area of the pregnancy test stick, if a positive reaction occurs during the test, and a red line is shown in the T-zone and C-zone of the stick when the stick is valid, then it means pregnancy. Blood can also be drawn to check the level of human chorionic gonadotropin in the blood, if the value of human chorionic gonadotropin in the blood rises significantly, it means pregnancy. After intercourse, you should always pay attention to your menstrual cycle and go to the hospital for testing if your period is delayed, and your doctor should inform you of the specific test.
