So I’m 21 and i just started taking birth control pills on October 1st. i mainly got on them because my periods have always been irregular and i was tired of it. i do have sex with my boyfriend but we always wear a condom and he never even finishes in the condom in me because i have bad anxiety and know i’ll freak out lol. but Im on my second set of pills now. I had my period and it was normal just lighter. i’ve been off my period for about a week now, and i have like bad back pain that feels like cramps almost. could i still just be getting use to the pills or could something be wrong? i didn’t know if it was like something super serious
