Anytime you have sex you run the risk of getting someone pregnant. This is why you should always use some kind of barrier method (such as a condom) while you are having sex. Of course, the only 100% effective form of birth control is abstinence.

The environment is not favorable for sperm when a woman is on her period, they were probably flushed out. I would say she is probably not pregnant, but remember anything is possible.
