Welcome to HCM.
The window period for HIV infection is 6-8 weeks after the exposure. So you are almost sure that you are not infected with HIV.
In rare instance it may be delayed up to 12 weeks after the risky contact.
If your HIV test remains nonreactive even after 12 weeks you can be 100% sure that you are free from HIV infection.
