Welcome to e health forum.

The chances of infection to a male, due to a single exposure , via vaginal intercourse is very low, to result in a positive infection. The risk is further lowered when the individual has used a condom, even if there was a breakage.

In eventuality the possibility of infection, depends the actual duration of exposure of the exposed mucus membranes of your penis, the amount or viral loads in the vaginal secretions of the woman (suspected to be HIV positive).

As per CDC recommendations, the only test used to screen for HIV is the ELISA test, which detects HIV antibodies in the body secretions and or blood. The 4th generation ELISA tests for HIV, detects both the HIV antibody as well as antigens of HIV virus. Hence the test that is very accurate and sensitive at detecting HIV infection. ‎This test can be done after 4 weeks of exposure. If found negative, the test should repeat it every 4 weeks until 12 weeks. ‎

In case the test results are negative after 12 weeks, then you can consider yourself as HIV free.

In your case, it would be recommended to do the HIV antibody test after 12 weeks (84 -90 days) and if this test is negative, it could be conclusive that you are free of HIV.

I hope this helps.
