Suggest Treatment To Cure Brown Vaginal Discharge And Irregular Periods

Hello, I have very irregular periods and they are once, twice or even three times a month. I very rarely have time off from them or a grainy, brown, sometimes stringy discharge. How do I make this stop. I am 44 yrs. old, a little over weight, but other then that in pretty good health. I have had pre-cervical cancer cells, biopsied and a coneoscopy to remove a part of my cervix. I also have been told I have HVP, which I do not understand. Help
