Unlikely: It is not likely that you are pregnant but it is a risk any time you have unprotected intercourse. Check a pregnancy test to be sure and then get in and get started on a reliable method of contraception. Use condoms too to decrease the risk of STDs. Best wishes.

Sure you may be: BUT unlikely...however too early to tell.... A pregnancy test is needed! (Your Pharmacist will assist you in choosing a reliable OTC unit) Good luck Hope this helps Dr Z

Take a test: You can buy OTC pregnancy tests at the pharmacy. The tests are very accurate. You may want to schedule an appointment with a Gyn for pelvic pap and Std check. It might be a good time to consider contraception. Stress reduction advised.
