Hi,
Welcome to HCM.
As far as HIV1, which is commonest HIV infection, is concerned you need no further test, as your P24 antigen test was negative after 4 weeks of risky exposure.
Your antibody test was negative after 65 days would not be sufficient to overcome the window period. A negative antibody test after 90 days would rule out both HIV1&2 conclusively, even though the chances for HIV 2 is the rarest possibility. So repeat the antibody test once again after 12 weeks of your risky contact.
