"okay, so if your on here freaking out like i was.... stop. seriously! okay so me and my boyfriend had unprotected sex while i was fertile, he did pull out but pre cum is just as effective. so i freaked out, and bought plan b one step and took it 21 hours later. i felt nothing. no spotting, just my boobs were sore and i was tired and moody. i was expected to ovulate around that time too so that just made it worse, since it&#039;s less effective if you take it after ovulation. so soon enough i got my period the day before i was supposed to get it! my cramps are worse than usual, but it&#039;s better than being 18 and pregnant. learn from this experience! but chances are your fine, so relax and go order some dominos cause plan b will do its job"
