Chances

Hello people i am a male and a while back i had unprotected vaginal sex with a fsw once. I havehas a hiv duo 12 days and 48 days after my exposure and both came out negative. Also i tested negative for all other stds.
My question is what is the likelihood that i could still be hiv positive? As some r argue a 4th gen test after 6 weeks is conclusive.

Your conclusive test result is 3 months post exposure. There are no tests marketed or sold to give a conclusive negative test result earlier than 3 months post exposure.
