I started new birth control pills to help me start my period after not having one for 6 months. It started right before I took the pills and ended like a normal cycle. After a week of taking the pills I started again. This time it's increasing the blood flow. I've been on it for 3 weeks now and it won't stop. Example, I'm having to change super plus every 2 hours. Extremely heavy. I've never had to do that before. Should I be concerned and take myself off or finish my pills for the month? Or next 2 packs?
