Again I'm so sorry for you Nicolle.
I had my third missed miscarriage earlier this year, with that one I couldn't quite believe the baby had gone and so opted to wait it out with a natural miscarriage. I didn't need to wait long, a week later my 7 week old sac (9 weeks pregnant) came, it was all over within a couple of days for me and like the previous poster has said it was on the day my AF would have been due. I had no further bleeding than those 3 days of miscarriage but it took a further 6-7 weeks for me to ovulate, and AF didn't show up either. It was a painful blow waiting for my body to return to normal. I caught that time again but unfortunately had another missed miscarriage, this time with twins.
I waited a few weeks but couldn't handle it any longer, I opted for a D&C and under the circumstances it was the right thing for me. I knew they'd gone and wanted it all over. I fell pregnant only a few weeks later and I'm currently optimistic about this one.
You need to think of the method that's right for you. Both the D&C and natural method were right for me at the time I opted for them, as my situation and mind needed the natural when I couldn't let go and the D&C when I had already let go and wanted it all over.
Sending you lots of strength and hugs, please feel free to PM me if you want to with any questions etc xxxx
