According to WebMD, a molar pregnancy is when what would usually become an embryo instead forms a benign tumor in your uterus. When this occurs, your body exhibits signs of pregnancy.

Molar pregnancies are very rare and only happen in 0.1% of pregnancies, according to the American Pregnancy Association.

There are two types of molar pregnancy: complete and partial. Molar pregnancies are caused by a problem during fertilization of an egg, according to the Mayo Clinic. There are two ways this can happen. First, an egg without genetic information is fertilized. This is a complete molar pregnancy. When a complete molar pregnancy happens, the growth can never become a fetus. Second, two sperm can fertilize an egg. This is a partial molar pregnancy. This growth may become a fetus, but it will most likely have extreme defects.

Although molar pregnancies are rare, there are several factors that may increase your risk. Your risk is heightened if you become pregnant

  • After the age of 35,
  • When you've had two or more molar pregnancies before,
  • When you’re had miscarriages before, or 
  • If you don’t eat enough carotene, which is a type of vitamin A.
