I'm just curious as to how long you bleed for a MC I'm not looking to be in an argument or hurt anyone's feelings but I'm just curious...I had some bleeding that concerned me so I went to the ER right away and they did a pelvic exam and said my cervix is completely closed that the blood is old blood, but I'm still just curious as to how long you bleed. My bleeding lasted maybe 5-10 minutes. I thought I was 6-7 wks and they told me I'm only like 4 wks so maybe I just ovulated late?
