Symptoms are not the way to know if someone is HIV positive or not. A 4 week negative test is encouraging with 80%. Get tested at 6 and 12 weeks to put your anxiety at rest and move on with your life. Good Luck and all the best.
Sex with a stranger, I believe I heard a condom being put on but I can't be sure, I was drunk. Sex for less than a minute but I know the amount of time doesn't matter. What do you think is going on? I never had any fever, sore throat or rash but I do have headaches that are lessening, a little nausea still, diarrhea, a little lymph node swelling.
