Chemical Pregnancy: Causes, Symptoms & What to Expect

Chemical pregnancy occurs when a fertilized egg implants in the uterus, but fails to develop into a viable embryo. It is common and typically occurs before a woman even realizes she is pregnant. Symptoms may include light bleeding or spotting, mild cramping, and a missed period. In most cases, chemical pregnancies do not require treatment and the woman's hormones will return to normal within a few weeks.
