You took PEP for oral. Oral was not a risk for HIV. You never needed the PEP in the first place. I don't know if your anxiety was so over the top when you saw the doctor that she was just trying to appease you and get you out of the office of if she is sadly uneducated, but she was wrong to ever give you PEP. You messed nothing up because you never needed the PEP. That's it. No risk, never needed PEP, and sorry this doctor (and you) put yourself through taking it.
