How does the pregnancy tests work? Except for ultrasonography test, all these tests work on detecting the hormone called human chorionic gonadotropin (hCG). This hormone is only found in the body during pregnancy. About six to twelve days after fertilization, a fertilized egg attaches to the wall of a woman's uterus. The cells of fertilized egg produce hCG which builds up rapidly in your body. It doubles every 2 to 3 days in the first few weeks of pregnancy reaching a peak level by 8-12 weeks. Pregnancy tests detect this hormone in urine and blood.

When should I take the pregnancy test? You can take a pregnancy test any time after your period is late - that's when they work the best. You'll likely get accurate results from a pregnancy test one day after your first missed period. However, it's best to wait at least a week after your missed period, to be sure that you get the most accurate test results. The Pregnancy test is done before a missed period usually gives less accurate results. Sometimes a pregnancy test can find pregnancy hormones in your urine as early as 10 days after unprotected sex. But these results aren't super reliable, and you may get a false positive or false negative test result.
