Emergency Contraception
"My experience is different from many of the people posting here. I&#039;ve never been that good about tracking when I&#039;m fertile, but I do have very regular periods. Several months ago, I had unprotected sex a few days after my period ended and took Plan B within 72 hours. About a week before my expected period, I had very light spotting for maybe an hour. Then it stopped. Two weeks later, I still had not gotten my period, so I took a test, and it was positive. Please realize that while Plan B is highly effective (I&#039;d used it with success before and am wholeheartedly in favor of it being available to everyone on demand), it&#039;s not foolproof and shouldn&#039;t replace contraception."
