I was a receptive male, I don't know if the condom broke.
I had a RNA PCR at day 13 - It back negative
I had a 4th generation at day 16 - It back negative
Now, 26 days after exposure I got a tonsillitis with body pain.
What are the chances that my previous tests turn positive at day 28?
I'm really anxious that I turn positive at day 28 because of that tonsillitis. Could it be symptoms of HIV?
Your tests are conclusive, you have no hiv. Hiv is not diagnosed based on symptoms or lack thereof. Furthermore, I dont believe you have tonsilitis, go see a doctor for your symptoms, dont self diagnose.
If a condom fails it is a large rip down the seam and hangs in tatters so both of you would have noticed that instantly.
Likely your symptoms are because you are living with the fear that you are dying - but you aren't dying so see your doctor to see if he can help you relax.
