A duo is conclusive after 28 days. It is abnormal to test repeatedly for a disease that you are conclusively negative for. This is just an hiv prevention forum and you don't have hiv so you need to move on from that theory and stop testing for hiv.

You've tested conclusively negative twice therefore you don't have HIV. Symptoms are not used to diagnose HIV therefore your problem is not HIV. If you had unprotected sex you should've also tested for all other STDs before having unprotected sex with anyone.
Your PCR, ag and ab tests were taken at right time frame. They definitively rule out HIV infection. Your ailments are unrelated to HIV, please see a doctor for them.
