I also had a similar experience. My doctor knew she didn't get a good burn on the top of my uterus, so that could have been part of the problem. I also had a fibroid which seems to have been the main cause of my post-op bleeding. She tried a depo shot, but that didn't help. A D&C with myomectomy to remove the fibroid seems to have done the trick. No bleeding for three months so far. But I'm on a three month birth control pill, so I won't know how my first post-op period is for a few more weeks.
