In brief: 1:1500

The incidence of a molar pregnancy is about 1 in 1500.
If you've previously had a molar pregnancy, its about 1 in 150. In early pregnancy, the symptoms are much the same as a normal pregnancy. Sometimes you can have spotting or more severe nausea and vomiting. U/S at 5 weeks is not always reliable for ruling out molar pregnancy. Best wishes!

In brief: Molar pregnancies

Molar pregnancies are more common in Asian individuals and can be sometimes suspected by a rapid rise in the size of the uterus relative to known LMP gestational age.
At 5 weeks of gestation it is very difficult to confirm a partial molar pregnancy as the ultrasound if done will show only early gestational material. A chorionic villus or amniocentesis sampling later in pregnancy will be abnormal.
