It's unlikely if you had your period just a week ago, however, when you have sex, protected or otherwise, there is ALWAYS a chance of pregnancy. Condoms should be a must! Not only do they protect you against pregnancy, they protect you against STI's.

It's too early to tell if your pregnant. Your body wouldn't even know yet. Wait two weeks from the time you had unprotected sex and take an HPT, or home pregnancy test. You can purchase them, no matter what age you are, from a local pharmacy or department store (like Wal-Mart or Target). If you can't afford those, like the name brand one, you can purchase one from any dollar store. They work just as effectively.

Always make sure you wear a condom so this doesn't happen again.
