Anytime semen or pre-seminal fluid enters the vagina, pregnancy is possible. The bleeding you mentioned was most likely caused by vaginal irritation from the intercourse. However, some women do have a little bleeding around the time of ovulation, which would have been the worst time to have unprotected sex. If you are not using any type of hormonal birth control (the pill, patch, ring, shot, implant or Mirena IUD), we would have recommended that you use Plan B. Plan B is a pill that can be used after unprotected sex to decrease the risk of pregnancy. However, Plan B should be used within 72 hours of the unprotected sex. Since you are beyond the 72 hour period, we would advise you to wait and see if you get your next period. If you miss your period, take an over-the-counter pregnancy test. Use first morning urine since it is more concentrated and follow the directions precisely. In the meantime, avoid alcohol, tobacco, and drugs in case you are pregnant. Also, please use condoms and a reliable method of birth control to avoid a future pregnancy. Feel free to call one of our offices for more information about your contraceptive options
