Hiv has been around since the early 80s.
Testing methods have improved with many studies.
As testing methods improved the window period to detect hiv has shrunk.
With over 40 yrs of this disease there is now a mix of outdated, BS, and current information.
You had a DNA test, two forth generation tests that also looks for p24 antigen that precedes antibodies.
3 antibody tests up to 5 months.
Todays test for hiv are among the most accurate and sensitive out there.
I tested out to a yr because many symptoms and some ongoing made me feel like you.
Just think, two ppl who engaged in unprotected sex together don't develop antibodies? What are the chances of that?
You "more" than tested conclusively negative. You surf the internet and keep fueling your anxiety that your negative tests should remove.
If you and the woman you were with had no other risks during your testing period, you are both conclusively negative.
You both being negative confirms each others status if you can't trust science.
Work with your doctor with your concerns but you ruled out hiv.
