How long?

Jacqueline
I had a miscarriage last year, I didn't know the baby didn't develope past six weeks till it occurred at week 11. That was my third miscarriage the other 2 were at 5 and 6 weeks. With this pregnancy my doctor was giving me weekly ultrasounds, found that the baby's heart stopped at 8w5d. Doctor wants me to do a natural miscarriage but it's been two weeks and nothing has happened, I'm an emotional wreck, has anyone else had this happen? How long did it take for your body to do what it should?
