I had my first exposure in my life (unprotected vaginal) with a girl who is married. Her last exposure was with her husband on 30th March while my exposure was on 18th June. Although she is healthy I asked her to check her HIV status because her husband got married before and divorced. She checked her status on 3rd day and 45th after my exposure both are negative (ANTIBODY TEST) Again after 52nd day and 75th day (August) after my exposure both are negative (HIV DUO. The last test (75th day HIV DUO) been 150 days after exposure with her husband. I Also did TRIDOT on 28th day and HIV DUO on 40th day. Should I need to test after 90 days with DUO? Or already conclusive?
