"i am a 18 year old girl who had unprotected sex with my boyfriend. he didn&#039;t climax inside of me but i was still afraid that something might have happened so to be safe i bought a plan b pill, took it 2 days after having sex and waited. my period was supposed to come the next week and it was the longest wait ever. it was the day i was supposed to get my period and it still hadn&#039;t come yet. it was 11 p.m. and it finally came the day of. super happy and this pill works great."
