hi your problem could be coming from the hormones don't forget these push up your hormone levels till your body adjusts to them and things begin to settle down and these extra hormone put your periods out of whack again till your body settles down to a new rhythm. hope this helps you. good luck
could i be pregnant? . i started taking birth control for the first time a month from tuesday on the first day of my period which made it last about 2 weeks (when normally it is only 5 to 7 days). i had sex 3 times after that where we used a condom and he pulled out (and the condom never broke). however while on the placebo pills i never got my period and now that i have started a new pack i still have yet to get my period. 2 preg. tests came back negative but i took them on monday and wednesday was that 2 soon?
