I had unprotected oral sex with another man of unknown status. He told me he didn't have any std but idk if I believe him. He didn't ejaculate in my mouth. I got tested for stds including a 4th generation hiv test at 29 days and they all came back negative. Then I did an oraquick test right at 90 days which also came back negative. I got another 4th generation test at 92 days and am waiting for the results, how likely is it that this test will turn out to be positive?
