Any time you have unprotected sex, you risk pregnancy. There is still a chance, though it is very small, that she got pregnant. If she starts birth control now, it won't help you with last week's sex. Have her take a pregnancy test two weeks from when you had sex, but not before, because it won't give you accurate answers. Next time you have sex, be sure that either she's on birth control, you use a condom, or both, because I'm assuming neither of you want a baby right now.
