Overview

Molar pregnancy is a condition in which the placenta does not develop properly. The symptoms of molar pregnancy, which may include vaginal bleeding, severe morning sickness, stomach cramps, and high blood pressure, typically begin around the 10th week of pregnancy. Because the embryo does not form or is malformed in molar pregnancies, and because there is a small risk of developing a cancer called choriocarcinoma, a D&C is usually performed.[1]
