"i had unprotected sex on tuesday the day before my period was due and my boyfriend pulled out but then we went for round 2. in the moment i didn&#039;t think about the leftover semen. but 68 hours later, i took the plan b pill. i waited and stressed about whether or not i would get pregnant. but after about a week after taking the pill, i had brown spotting and then later that day i got my period! i&#039;m so glad to say that it really worked for me."
