If you have unprotected sex just once, your risk of pregnancy is quite low. However, you can reduce your risk even further by taking Plan B (the morning after pill) within 72 hours of the unprotected sex. Each time you have unprotected sex, your risk of pregnancy increases. If you continue to have unprotected sex regularly over the course of one year, your chance of pregnancy jumps to 85%. Nine out of 10 sexually active couples who do not use birth control will become pregnant within a year. That’s why it’s so important to use birth control if you do decide to have sex.
