My little one is 9 months old, and I'm still having some bleeding between periods. It happens about mid-cycle. I called my ob about it, and he said it's just (and this definitely puts us back on the gross side!!) "old blood" from the pregnancy. Ewwww. Anyway, he said it can happen for a few months after you stop nursing and that it is completely normal. However, considering your situation of the doctors having difficulty stopping the bleeding during surgery, I definitely would call the doctor right away. One of those better-safe-than-sorry situations! Might as well be sure it's nothing to worry about so you can put it out of your head. Have fun with your son. Congratulations!
