Sorry to hear of you loss/es babygiraffe.
TMI warning - When I had my first MC (natural/complete) I was 7 weeks and I didnt have a lot of pain but after bleeding for about 5 days,it came out as a big blob, all in tact. I had a scan a few days later when the bleeding had nearly stopped to make sure it had all passed, in which it had.
Everyone is different but maybe for peace of mind you could get a scan done?
Big hugs to you
