I had a mmc in january. I had an erpc at 11 weeks (pregnancy measuring 6 weeks) on the 30th Jan. I haven't had any scans or tests from the hospital since my ERPC. I did go to them 4 days after my surgery with heavy bleeding, pain and dizziness but they said it couldn't be retained tissue because I wasn't in enough pain. Yesterday I passed this chunk of tissue. The picture isn't good. It was grey tissue with some blood on one side. Is this retained tissue? I was still getting very faint positive tests so I'm guessing it was uterus lining possibly as it was 7cm long which seems quite big for a pregnancy measuring 6 weeks?
