I missed the last 3 pills... (Thurs, Fri, Sat) of week 3 in my pack. I usually start my periods on Tuesday morning, but I started today (Monday). I'm not having sex, so I'm not worried about getting pregnant, but I'm wondering what to do. I read you are supposed to start a new pack, but I would be starting my period tomorrow anyway, should I just let it run its course? Or will I bleed for weeks? Should I just start the new pack? Help!
