Having sex during a period does not usually result in a pregnancy, as long as the bleeding you experienced was truly your period. However, everyone is unique and anything is possible. Withdrawal (the pull out method) is not an effective method of birth control for two reasons. First, pre-seminal fluid can leak out of the penis prior to ejaculation. Pre-seminal fluid sometimes contains sperm. Second, sometimes it is difficult for a guy to remove the penis from the vagina before he begins to ejaculate and some of the semen is deposited inside the vagina. To be on the safe side, you may want to use Plan B within 72 hours of the unprotected sex. Remember that Plan B should only be used in the event of an emergency. If you are going to continue to have sex, please consider using a more reliable method of birth control. You can call one of our offices for an appointment. We would be happy to discuss your options.
