Bleeding For 90 Days

As of today I have bleeding for 90 consecutive days & I feel so depressed about it. Birth control is not seeming to help as the bleeding is not changing at all & I am mid way through my second pack. This past week. I have been to the doctor maybe 6 times in the past 2 months regarding this bleeding. My mother has mentioned a drug called lysteda. Do any of you ladies have any experience with this medication? Or if you've ever dealt with prolonged bleeding what did your doctor give you?
