Pregnancy test(HCG)
There are two main types of pregnancy tests that can let you know if you're pregnant: urine tests and blood tests.Both tests detect the presence of a hormone called human chorionic gonadotropin (hCG). hCG is made when a fertilized egg plants itself in the uterus. This happens approximately six days after the egg and sperm unite. It is this rapid shift in hormones that triggers most of your pregnancy symptoms.
