bleeding for 6 weeks every day non stop

I was wondering if anyone else has experienced the same as me as im going out my mind with worry. Ive been on the rigividon pill on and off for years now prob nearly ten years i have just started in the last six weeks bleeding constantly fresh blood every day having to wear pads i bleed after sex,orgasims, going to the toilet just any pressure down there i bleed. I went for a scan today and said they could not see anything. I had a cervical screening smear two yrs ago now just no one or gp seems to listen or understand that this has never been normal for me. Any infor would be good or similar experiences thanks
