pregnancy testing
Pregnancy testing checks for the presence of the pregnancy hormone, hCG or human chorionic gonadotropin, in your body. This hormone is produced within days after implantation, when the fertilized egg attaches to the wall of a woman's uterus. This usually happens about nine days after fertilization, with a range between 6-12 days. If you are pregnant, levels of hCG continue to rise rapidly, doubling early on every two to three days.
