Your tests are conclusive and you do not need to test again. Even the older tests are reliable and accurate at 90 days and any time beyond.

As an adult, the only risks for HIV are:
1) having unprotected, penetrative vaginal or anal sex, or
2) sharing IV drug needles with other IV drug users.
Whatever is causing your symptoms is not related to HIV.
