"if you&#039;re a teen like me and you were bein stupid and didn&#039;t use protection you&#039;re probably terrified. i was too. plan b works 100%. don&#039;t stress it. you will get your period. stressing with make it late. i took plan b an hour after the occurance and got my period 9 days later. use protection. be careful but if you&#039;re not. this is a great back up plan for a mistake. you&#039;ll be okay. take it with ginger ale though because it makes you have a bad tummy ache. better than being pregnant."
