3 years ago, I had a partial hysterectomy for the same condition. For 6 months, my doctor tried to avoid it, but birth control pills didn't keep me from bleeding constantly. So, I had no other choice but hysterectomy. I had multiple fibroids in the uterus, though.
Good news: now they have a new proceedure called "Hysterectomy Alternative". They don't remove any organs, just calderize the uterus and close the cervix. Has the same effect.......no more periods, no more pregnancy, too, though. Ask your doctor.
If you're just having break thru bleeding, try changing to a very strong bcp for a couple of months.
Hope this helps!
