A week ago I had heavy bleeding for 3 days. I was 2 weeks past o and afraid it was a mc. I can't go to ER cause my insurance is being transferred and my doc can't get me in untill the 11. The day I started bleeding I had a neg on a Walmart test and last night I had a pos on a Walmart test. After having pos on frer. Do u think I had a mc? Or was it just a membrane in my cervix?
