"Had unprotected sex a day after my period ended and took Plan B 10 hrs later. No one told me it would make my period come again 5 days later. I looked up side effects and everything said if you bleed before your normal period then you may have an epitomic pregnancy. I&#039;d never been more terrified in my life. Thanks for this forum or else I&#039;d think something was wrong with me. So glad to see that it&#039;s normal."
