Having a miscarriage and just need answers...

Dr confirmed that the heart stopped beating before 7 weeks. I am heart broken, but I had a week to prepare for this after our last visit.

Right now my main concern is my health.

I am simply terrified and do not want to have a D&C. I just want this to pass naturally. My question is.. how long will it take? How long before the bleeding starts and this will be over with? I just dont want medical intervention after all we've been through. Any stories, common cases, statistics are appreciated
