I've been on birth control for about 5 months this is my 2nd brand. this one has been working fine for 3 month

but just last night i got my period for the 2nd time this week. I take my pills the same time every day and i never miss a pill. I'm not sexually active and i went on birth control because i get very bad cramps. Why is this happening?

wow i can relate, well when i was younger, what the dr told me was my body is going to take a lil while to adjust, i was on like 4 different kinds, until my body adjusted, some i had to stay on for like 3 months and they made me so sick, it sounds like this one isnt really working, try the patch, at least its only once a week thing it worked really good for me,if not well seek a second opinion from a different dr. good luck
