I had receptive and insertive oral sex on the 24th of August 2021 with no ejaculation. However, I had bleeding gums. I developed a sore throat and swollen glands (no fever or rash) on the 6th of September, and it’s only become worse since then. I’ve already taken two courses of antibiotics but the tonsils have been growing and so have the cervical lymph nodes. I tested positive on VDRL (syphilis) but negative on HIV card test today (almost six weeks). How likely am I HIV positive?
