30 days ago I had unprotected sex with a 23 spanish girl in Barcelona. Specifically we had unprotected oral and vaginal sex for about 5 minutes. I took a p24 antibody/antigen test 18 and 30 days post exposure. All 3 turned negative, can I relax? I'll still have a 3 month test but I'd like to know what are my odds of actually turning hiv+ after the 30 day mark. I've been very very stressed, I've had foggy mind and dizziness for over 5 days, are these symptoms related to the stress or fear of having hiv?
