I've been on a generic form of seasonale for a little over 15 weeks and at first it I was fine . I had side affects but no breakthrough bleeding . I skipped my week of sugar pills because I wen on vacay and it was fine at first but now I've been bleed for a good week and a half maybe more . And my cramps have been very painful but not the worst I've had . I don't know if this is happening but of me skipping the sugar pills . What's happening ?
