Molar pregnancy

Has anyone on here had a molar pregnancy? I thought I had a missed miscarriage when I went in for my first prenatal appointment 2 weeks ago and there was no baby. I went in for follow up scans yesterday and my doctor said that he thinks I may have a molar pregnancy. I'll be getting a d&c next week. But I just have a few questions. I don't really know what to expect. If you've had this, did you have any problems with the cysts coming back? How long did you have to wait to try again?
