IT depends on when your ovulation will start. If you have a short cycle, like 24 days and if your boyfriend came inside of you, you could be at pregnancy risk.

However, if he didn't ejaculate, the chances are minimal.

Also, if your cycle is 30 days long, then the chances are also slim.

If you are on your period, you cannot get pregnant, so I've heard.
Probably there is a veeeeeeeeeeeeery small chance, therefore nothing to really worry about.

I guess this is more for anyone doing some research now, since this was posted in 06. But here goes: I've been researching this all morning because I'm in a similar situation, though I'm definitely still on my period and my boyfriend did come inside me. From everything I've read, the chances of getting pregnant on your period are reduced, but it's still possible. And the chance is greater for pregnancy if you have sex at the end of your period. Like Jannie said, it depends on when you'll ovulate next. So if you had sex on the last day, depending on your cycle, you could release another egg as soon as 5 days after you had sex. And considering sperm can live for up to 7 days in the vagina, you could be taking a pretty big risk. Emergency contraception is an option up to 5 days after having unprotected sex. After that, abortion within 3 months. Or you could always keep the baby, give it up for adoption, etc. There are lots of choices to make.
