I had an unprotected vaginal sex one time on July21, 2018 with a guy who claims is HIV negative but I don’t know if I could trust his word. Since then I have had 2 HIV tests done one on 35dayd- Alera Determine HIV 1/2 ag/an Test which was negative then another test at 46days HIV 4th Generation combo test - negative results. But It was recommended that I keep testing every three months until the end of the year just to ensure I am negative. This has made me very scared and I can’t sleep, I am imagining things and I am terrified. Are my negative results a good indicator that I will remain negative or should I keep testing ?
