Hi doctors, I have a question about PEP. Is it possible to infect my partner while I’m on PEP, but myself subsequently test negative 4 months after completion of PEP? In other words, can I have had hiv while still taking pep, gave it to my partner through sex while on pep, then later test negative myself since the PEP ultimately worked for me? 

It is that you are the same person who posted previously as John Phillips and has been repeatedly reassured that it is IMPOSSIBLE to infected a partner with HIV while taking PEP and then to subsequently test negative for infection.---
