I experienced the same thing with heavy uterine bleeding. It was horrible and I also became extremely anemic. So anemic I had to have blood transfusions just to have the surgery I needed. Turns out I had a uterine fibroid. Since I was still young enough to have kids & had none I had a myomectomy, which is just the removal of the fibroid while leaving the uterus intact. I had a second surgery about a year later because of endometriosis. So I understand some of what you're going through. I didn't have a problem with the surgeries themselves except they ruined my stomach muscles and now I have a huge ugly scare.

My operation gave me so much relief I really think you should reconsider canceling your appointment. From what I've read a Hysteroscopy is a far less intrusive procedure than what I had. I wasn't able to because of the size and location of my fibroid.

Have you considered talking with the doctor about how upsetting this surgery is for you because of your past. Maybe if they know of your experiences they will be more understanding. I hate to think of you not having the surgery. Once it is over with, the relief should be significant.

I really hope you can get this all settled. I would have your bf go with you to your appointments for support.
