Missed pills: Likely missed pills and now with withdrawal bleed. Couple options: Stop pill for 4 days, allow for bleeding, then restart new pack. Next is get rid of sugar pills, take 3 pills x 2 days, 2 pills x 3 days, then take one pill daily. When you take birth control pills you do not have 'periods', you can completely control when you choose to bleed.
