Did she have her period before or after it broke? The time right after a girls period is the time she is least likely to get pregnant. And if she has had her period since then she is fine. If you are still worried when it is time for her period or a few days after if she is late have her take a home pregnancy test. If it hasnt been to long you can still use emergency contraption.

Girls are fertile to concieve between days 10 and 14 after the first day of their last period. So ask her when the first day of her last period happened to be. Take a pregnancy test. It's actually hard to get pregnant if you think about it because you have to time it correctly. So in retrospect, if sprem was inside of her up to 72 hours before she ovulated then there's a good chance she could have gotten pregnant.

It's probably too late now but there's the morning after pill that would have needed to be taken within 72 hours after intercourse.
