From one act of unprotected sex, you have about an 8% risk of pregnancy. If the intercourse occurred around ovulation time, the risk would be higher. If you regularly ovulate mid-cycle and you have 28-day cycles, you would have ovulated approximately 14 days after the beginning of your period. I wouldn’t stress out too much. You used a condom and it sounds as if the condom did not break or leak during use and you also used Plan B to further reduce your risk. If you are a week or more late for your next period, take a pregnancy test. However, pregnancy is highly unlikely in your case.
Just remember that Plan B should not be used habitually as a regular method of birth control as it is less effective than other methods. If you are going to continue to have sexual intercourse, you may want to think about using a hormonal form of birth control as they are more effective.
