I took plan before hours after sex, then 5 days after I took the plan be I had my period, or what I think was my period! I had heavy bleeding & cramps for 5 days! Then 7 days after the end of my period I started birth control. I'm on my second day of taking it. Does anyone have any idea when I should start my period? Do you think there's a chance I could be pregnant?

Any time you have sex, pregnancy is possible. Plan B isn't 100%, nor is any other form of birth control or pregnancy prevention. So we really can't tell you if you're pregnant or not. Based on your posts, you're taking a lot of risks.

Birth control like the pill, isn't effective for at least a month after you start using it. Even after a month it's not 100%. You could use 3 or more forms of birth control and still get pregnant if you're having sex.

You took plan B, one of the side effects of that drug is that it can mess up your period. So really, no way to tell you when you'll get your next period, or if you're pregnant. You're putting your body through a lot of stress, and it may rebel.

Good luck.
