I keep bleeding every month and the bleeding is heavy. My Physician just kept switching my hrt and doing nothing else to resolve this issue so I switched Physicians. I had a Pelvic and Transvaginal ultrasound and residual ovarian tissue was found and the size was almost as big as a normal ovary. Besides being mad, I am concerned about having a ovary (basically) and still taking hrt...does anyone have knowledge of whether or not this was dangerous?
