I've been on the pill 21 days, and I took the last one before a 7 day break of Saturday morning, its now Monday and I still haven't bled, is this normal? Also how long do you bleed for? I am going away this weekend and really cannot afford to be on my period. I was wondering if I could start the pill a few days under 7 days, for example Thursday or Friday, would this stop my period for the weekend? Or providing I eventually come on, would the pill not stop the bleeding once its started, please help as I REALLY can't be on this weekend! Thanks
