There are no tests approved to give one a conclusive negative test earlier than 3 months post exposure.
Dear Teak,
I found this post by Dr. Hunter where he says 2 months is enough, how come?
Isn't it like that after 2 months its 96% reliable after 3 months 99% after 6 99.5% and after twelve months 100%, Why else would he, as a leading figure in the STD field say 2 months.
Sincerely.

Relax. With a negative HIV test 2 months afterward, you can be 100% certain you did not acquire HIV during the sexual encounter you describe. Sinus symptoms are not like those of acute HIV infection;....
3 months is when you can obtain a conclusive negative result and that's Worldwide.
