periods and bc

Lauren • i like soft pretzels and u :-)
i plan on talking to my mom soon about going to the doctor for my period pains bc my cramps are so bad that i faint and feel sick to my stomach and sometimes even throw up. by doing this i want to be put on birth control for the periods and for its actual use. however, is the pill the only form of bc that would make sense to use for my period? because my mom won't know about the fact i'm sexually active, she'll just think its because of my cramps, but i'm so forgetful i don't think the pill would be a good choice for me... i hope all of this made sense lol
