Pregnant, if i had sex the day before my peorid was due?

I think youre fine but im having a similiar problem, i dont wanna get my hopes up :(

There is only a slight possibility that you can get pregnant the day before your period is due. It can take a while for the sperm to swim up to fertilize the egg. You're fine though. Don't go out and buy baby clothes or anything like that. If you were pregnant your period wouldn't come or if it did would be very VERY light and only last a day or two. Just make sure from now on that you use a condom and are careful. If you're still worried, use a spermicide (but make sure it's not going to eat through the condom).
