1st miscarriage, 2nd D&C, and molar pregnancy

I just had my 2nd D&C today and the test results from the first one came in yesterday and they determined I had a partial molar pregnancy. Has anyone had this happen? They ordered 15 weeks of blood tests. How long did you all have to take the blood tests before your HCG was low enough to try to conceive? How long before your doctor let you try again? Also, did anyone have to take methotrexate or worse?
