Moms, a TMI question?

i wouldnt just cuz i dont agree with birth control. last summer i didnt have my monthly for 3 months before i actually got pregnant, wasnt on birth control neither was my boyfriend doing his part. now im on the shot after the baby was born. it screwed my cycle. i got te depo & it made me bleed for 26 days, stop for like a week & im on the monthly again. so mines all screwy. the only reason im on it is for my boyfriend. but i personally think it doesnt matter whether ur on or not cuz it wont do anything for u
