General Surgeon Dr. Rajinder Bajoria's  Response
Welcome to health care magic
HIV has very long & varied incubation period ,so Elisa( forHIV) negative even up 3-6 months is of no significance.So after unprotected sex one should be watchful ,as tension & worry don`t help instead they aggravate things.If still not sure go for western blot test.
Wish you speedy recovery
