This is my second pregnancy but only my first birth. I lost the first baby at 7 months. That was about 10 years ago.
With any issue, you can always get a second opinion. I would, if I were in your shoes. My sister has a friend that had her son in Feb. 2008 and bleed for the entire year before she became pregnant again with her daughter. I know that birth control pills worked for her but when she was off them, the bleeding started again and continued. Is this your first child? I'm wondering if this happened before with another child too.
