Hello You had sex you ejaculated or not ejaculated , this is not a protection for you . You had unprotected sex , so risk was at peak , IF the lady was an HIV infected . If she was free from HIV , no need of worry at all. Since you are in tension so this test will relieve your tension. Get in P 24 nucleic acid amplification test (pcr rna ) rapid . Western blot is the most commonly used confirmatory test and detects antibodies to HIV antigens of specific molecular weights. Antibodies to HIV begin to appear within 2 weeks of initial infection ( contract with that lady ) and the period of time between initial infection and development of detectable antibodies is rarely more than 3 months. In your case after 2 weeks of initial contract get in blood examination for NAT ( as mentioned above). Bur in my opinion you are HIV free.
