I had my d&c 7 weeks after the initial miscarriage - there was hardly anything left, but I had been bleeding so long that I begged the ER doc who was doing the scan to just give me the procedure. Once he was happy that I understood the risks, he booked me an appointment for 2 days later. If you want the procedure now, talk to your OB and get him to book you in - there's nothing wrong with changing your mind hun
