"i started taking sprintec to avoid pregnancy and regulate my periods. i finished 2 packs already and i just started my third this week. i started the pack two weeks after my period and i did get my period 2 weeks late but it was super heavy the first two days and i have really bad cramps. i got my period late again last month but that was my fault for not keeping up with my pills and my period wasn&#039;t as bad this time. it&#039;s the third month and now i noticed that i gained weight but not a dramatic amount and i have gone up a size in my bra cup and my underwear and jeans. i do tend to get moodier than what i used to but it&#039;s not as dramatic. that&#039;s only been about 3x. my sex drive has not changed. it might have even increased a bit. i&#039;m 19."
