Just over 45 days ago, I had unprotected insertive anal sex (I was the top) and rimmed a transgender woman. She indicated she was on PrEP as well and tested every three months, but never know for sure. I got really sick several days after this. Fever, sore throat, muscle cramps, chills, blood in stool. I believe it was the rimming that caused this, maybe a bacterial infection, but don’t know for certain. First time this has happened to me. Really shook me up. It eventually cleared and I just did a panel of STD tests at 45 days. Everything has come back negative thus far. Believe they’re still working on the chlamydia and gonorrhea. I’m curious as I’m on PrEP, is 45 days from exposure conclusive for a fourth gen HIV Ab/p24 Ag with Reflex test? I’ve seen conflicting information online that PEP/PrEP can delay the true result and to retest at three months. Is this true? I wish I would have known this and asked before this.
