Help!!!

Fancy Nancy
I have a mild form of polycystic ovarian syndrom and a while back I was having heavy random bleeding and so my doctor put me on medicine and it eventually stopped the bleeding and I finished all the medicine. But 2 days ago, I decided to one of those pills up there that makes the smells go away (I've used it before and it works just can't remember the name) and almost immediately I noticed spotting. Throughout the day it moved on to like full blown niagra falls and it was almost like my period, which I haven't had in months due to psos I had pretty bad cramps. But anyways, I wanted to see if there was someway to stop the random bleeding? Should I start back up birth control (the pill)? Will that regulate it? I just can't keep bleeding.
