I had unprotected vaginal intercourse with a woman I assume is HIV positive roughly 20 days ago. This lasted 3-5 minutes and I am circumcised. I had no cuts on my penis and did not have an STI at the time. I have not taken PEP.
I received a 10 panel STD check (including the 4th generation HIV test) at 14 days post-exposure and everything came back negative. I then took an HIV RNA test 17 days post-exposure and will receive the results within a couple of days. I understand I need to wait a while to test again for HIV for any of these tests to be conclusive.
I have read that the 4th generation HIV test can detect the p24 antigen as soon as two weeks, how encouraged should I be that I tested negative? I understand it was too soon for antibodies to show up.
I have not experienced ARS symptoms, should I be encouraged?
I plan on taking the 4th generation test again at 28 days post-exposure, is this appropriate?
Thank you for any replies.
