Been bleeding for 7 months straight, looking for suggestions besides what i've tried that i can look into?

Hey, before you decide to criticize i'm taking matters into my own hands. I'm just looking for ideas to look into. I've seen my family doctor, and gyno with no results. I've been on birth control pills, and depo shot since i was 16, and im 20 now. ive never had a consistant period in my entire life, but over the last couple of years i began bleeding through the pills, suffered constant infections, and was told i have severe abnormal cells with the possibility of cervical cancer to be determined at a later date. I've been bleeding everyday for 7 months straight. Nothing has stopped it like i said, and the doctor has told me i cant use the nuva ring (because it'll increase my infections caused by the pill because its the same hormone) and my only other option is a minimum $350 UTI Mirena (which is expensive for a hunch). Im looking for any suggestions for suppliments, dietary ideas, anything you think my decrease the bleeding. Its depressing and im sick of it.
