Hello again Anon
It sounds like you've had a battery of tests but you are bleeding excessively, even for someone who may be in early menopause. I assume you tested negative for fibroids.
Fibroids are benign (noncancerous) growths in the wall of the uterus. The uterus is the reproductive organ where a fetus grows. Fibroids often grow into the uterine cavity. In rare cases, they may protrude from the uterus toward nearby organs. Fibroids may be very small or may grow to eight or more inches in diameter. Usually more than one fibroid is present. About 20%-30% of women of childbearing age, and as many as half of all women, have fibroids. Many do not realize it. Most do not have symptoms until their late 30s or 40s. However, if all your scans and tests are normal, you may not be dealing with this.
Contraceptives are for far more than birth control so it's a goo idea to try them to see if they regulate your system. If they don't work you may need to proceed with the cauterization.
I can imagine how frustrating this is for you - please keep us posted as to how things progress.
