Emergency Contraception
"Last month I took a Plan B pill about 12 hours after my accident. And I got my period a week early. I did have bad cramps, but the flow was normal. This month my period is about 8 days late. I have really tender breasts, and I get cramps on and off all day. If I am pregnant it&#039;s not because Plan B failed. I read other forums and people were saying that their second period after Plan B was either later or didn&#039;t come."
