im taking kariva birth control, partly because i have irregular periods. i was told to wait until my next period to start taking it, but i was wondering what would happen if i started taking it now. how bad are the side effects? ive looked it up and i cant find anything except a bunch of legal stuff saying do what your docotor says. i know its safe to do, so what would happen to me if i did take the pill too soon in my cycle?
