Missed MC - how long b4 d&c?

E.

For anyone who has had a missed miscarriage, how long did you wait before having the D&C;? I just found out last week (8w5d) that the baby stopped growing at 6w and has no heartbeat. We are doing another ultrasound next week just to be sure and then I expect the Dr. will suggest I schedule the surgery. I still have had zero bleeding and only minimal cramping. Also any advice for preparing for the procedure? Not looking forward to it. Thank you.
