I have had to take 2 different courses of antibiotics since december for bronchitis, I kept using my Yaz bcp since it was originally prescribed for PCOS, along with metformin. I didn't use any backup bc, and kind of have been having an upset stomach on and off for the last 2 weeks. I started an early period 6 days ago, it actually occurred just a week after I finished my last period. It started off bright red with discharge then continued into a dark brown color (sorry TMI). Is this implantation bleeding or just my body going wacko from all these pills???
