Of couse you are concerned for your own health. Early miscarriage such as yours is very common and has always been common, just not talked about. I had two early miscarriages, one which my doctor called a "blighted ovum" that eventually required a D&C and the other cleared naturally. Afterwards, I was amazed at all the neighbors and friends who shared their similar stories with me.
Unless your doctor advises against it, you might be able to wait to see if your body will handle this naturally over time. (I'm not quite sure if a molar pregnancy is different or the same as a blighted ovum.). My doctor let me wait almost 3 months before I decided to have the D&C. I had periodic bleeding but the remains of the miscarriage did not clear, so my hormones were off which led to acne and other icky symptoms. The D&C was no fun, but I felt better after. The second miscarriage cleared within a few days and I felt fine, so nothing more was needed. Soon after, I became pregnant with my daughter and had absolutely no complications.
