Threatened Miscarriage Overview

What is a threatened miscarriage?
A female with a threatened miscarriage has vaginal bleeding during the first 20 weeks of pregnancy. Vaginal bleeding prior to the 20th week of pregnancy represents a threat that a pregnant woman may lose the fetus. Vaginal bleeding that is accompanied by lower abdominal pain increases the risk for miscarriage dramatically. The most common cause of a miscarriage is abnormal development of the fetus.

What are the symptoms of a threatened miscarriage?
Symptoms of a threatened miscarriage include vaginal bleeding and lower abdominal pain.

How does the doctor treat a threatened miscarriage?
Treatment for a threatened miscarriage may include bed rest, plenty of liquids, and an injection of antibodies, called RhoGAM, in order to prevent erythroblastosis fetalis.
