You need another HIV test 90 days from exposure to make sure. Pl be careful next time by using prophylaxis.

Not all STDs are prevented by condoms. It would be prudent to see a doctor to make sure. HIV 4th gen combo test should be done 6 weeks after exposure to rule it out. HIV test window periods https://www.cdc.gov/hiv/basics/hiv-testing/test-types.html https://www.cdc.gov/std/default.htm
