It’s not possible to become pregnant one day after you’ve had sex. It takes up to a few weeks after sex for pregnancy to happen, and 2-3 weeks for a pregnancy test to be accurate.

However, if you had unprotected sex (meaning without a condom or other method of birth control), it’s possible that your girlfriend can become pregnant. If she doesn’t want to get pregnant, she can take emergency contraception up to 5 days after unprotected sex to help prevent pregnancy.
