A little backstory: I take my pills for 3 months straight and then get my period at the end of the 3rd month. So only 4 periods a year. They normally last 5-7 days, normal flow. This month I started my period not even half way through my "third month" pack. I continued to take my pills through so I didn't mess up my pill schedule and I'm still bleeding. 9 days later. Not heavy at all but enough to be annoying. What could be going on? I thought my period would have ended sooner with continuing my pills. Am I wrong?
