Terri, yes, the swab for the PCR was done before I started taking
famciclovir. I imagined that the antiviral therapy would interfere, so I had all my exams before that.
Answering your previous question: yes, my boyfriend does give me oral sex, but I've never noticied cold sores in his mouth.
The whole thing sounds very odd to me. I read everywhere that catching herpes from a one-time sexual encounter is very unlikely, specially when the sex partner does not show any lesion.
