If the viral load tests were negative you are probably negative. P24 is the most often cause for false positive antibody tests. Still, you should get another test in 2 more months to be sure, and only practice safe
The real question is why are you taking all these tests? All you need is a regular ELISA. As Thankful said, get that done in 2 months and trust the results you get.
(If the ELISA is positive and the WB is still indeterminate, that is a negative result)
