Building on what AnxiousNoMore has said, you need to get yourself tested for HIV Duo test anytime now , collect your conclusive report and move on with your life
I am not sure, where are you from. If your 8 weeks test was done on third generation test kit, it was highly reassuring but not conclusive.
In India and Pakistan, 4th generation Duo tests are commonly available with top ranking clinical laboratories.
Symptoms do not tell us anything, it is the test report that determines our status conclusively
A duo test is conclusive at 4 weeks, so if that was used you don't have to worry.
Doctors can't diagnose HIV from symptoms, so you won't be able to either so it is best to not study them.
