Stupidly I had unprotected vaginal sex with a sex worker. I panicked, went to the clinic and was put on PEP within 32 hours. I'm not sure about how large my risk was, and the doctor said my chances were slim but would prescribe to help my anxiety. Should I really be on these meds? She said she was negative but you can never be sure. This was a one-time thing and will NEVER be repeated!
