hello. i had a possible exposure to hiv 2 weeks ago. i had unprotected sex with someone i dont know with unknown hiv status it was my first exposure of this kind. 1 week later and i discover small purple cappilary like marks just under my chest on my belly, they are only few of them but are still present. 2 weeks later and i have developed a rash on my face like tiny bumbs but seem colorless, also along my forearm which do not itch. i have no other symptoms no swollen glands, sore throat fatigue etc just the rash today. it could be heat rash since i work in a very hot place the last week. i am waiting on a test in 3 weeks but can you tell me what your opinion is on it. and what is the likely hood if she was hiv positive that i caught it from 1 exposure and i did not ejaculate.
