My sister has this scar and had an implantation in it. Multiple D&Cs later they figured out what it was. This took over a year. Yes, your uterus can rupture and you and the baby are dead. Its truly terrifying. I am sorry he didn't catch it sooner PP.

If you feel cramping but are not bleeding I wouldn’t worry too much. However if you are in a lot of pain or are bleeding call your OB office. Any OB has to see patients if there’s an emergency, usually the same day. They just scheduled your routine monitoring for a few weeks out because you have already had what would be your first appointments with the RE.
