What is the earliest day after a missed period that a person can take a home pregnancy test and expect it to be accurate? Pregnancy tests are designed to tell if your urine or blood contains a hormone called human chorionic gonadotropin (hCG). This hormone is produced right after a fertilized egg attaches to the wall of a woman's uterus. This usually happens -- but not always -- about six days after fertilization.

Pregnancy Tests Overview This is known as the Chadwick sign. The uterus may feel softer, larger, and more round. Many women know they are pregnant before they see their doctor, however, because they perform a pregnancy test themselves at home. Nonprescription home pregnancy tests are available in any pharmacy and cost $10 to $20. These tests are designed to detect the presence in the urine of human chorionic gonadotropin (HCG), a hormone produced by the placenta shortly after fertilization.

- A special hormone, called hCG, is found in the urine of a woman that is pregnant, and is produced by the placenta. All of the tests, aside from blood tests, will use a woman’s urine to find a sufficient amount of the pregnancy hormone hCG. This hormone takes a few weeks to build up to a sufficient level for detection.
