We had our son two months ago and I received my first "period" on March 3rd and was still slightly bleeding when we had sex. We had unprotected sex late night/early morning 12th/13th and he did not pull out. I got the plan b pill and took it right away, between 11-1 pm. I started cramping the next morning and started bleeding heavily on the 19th and still currently am. I am also over the 165-175 "weight limit"; 207. I was wondering if the heavy bleeding could rule out pregnancy. Anyone with similar experience??
