I am 45 now, but when I was 42, I flowed for 17 weeks ( ) in a row! My OBGYN did an ultrasound, then a biopsy. (My family has a history of fibroids and polyps and all 4 of my sisters had to have a hysterectomy in their early 40's.)

They determined that my hormones were messed up. I was taking birth control pills at the time. They gave me a pill (can't remember what it was, sorry) to control the bleeding. I took it when I was taking the placebos in the bc pack. It took a few months to completely stop, but it eventually did. During that time, it was more spotting than anything else.

I feel for you, flowing for that length of time is awful! I hope that your OBGYN can figure out what the problem is and get it fixed.
