hi I am a man 22 years old I had a protected sex with a man. I was the receiver. after we done the sex, I did several tests. the first one was the combo test which is the p24 and the antibody on 21 days after the relation. then had the same test on 28 days. and the third test was the same too which is the combo test in 41 days after the relation. all of these showed negative. I also had an oraquick test in 71 days and it was negative. my questions: 1-was I at high risk? 2- do i have to retest again? 3- can I make sure that i did not catch the HIV? 4- is the oraquick test good?
