Hola guys
I gave an unprotected oral sex to a man with unknown HIV status in 2nd of september 2021 and i have an ulcer at that time and he ejaculated his sperm in my mouth. One month later i took a test and the result was non reactive. In 1st of nov 2021 i took a test anymore and ended up negative . That was my last time of testing i don't go test again yet. But, from december til now i've been feeling a sore throat. Is this HIV?
