I had an unprotected sex but I don't know the exact month. What will be the waiting period or after how many months will I come to know that I am affected with HIV positive or not?

If you can do blood test after 3 months you can know if you are infected .A nucleic acid test (NAT) can usually tell you if you are infected with HIV 10 to 33 days after an exposure. An antigen/antibody test performed by a laboratory on blood from a vein can usually detect HIV infection 18 to 45 days after an exposure. UK guidelines state that 4th generation HIV tests (antigen/antibody) will detect 95% of infections four weeks after exposure. A negative test after four weeks then needs to be confirmed with a second test three months after the risk. This is in case you take longer than four weeks to generate an antibody response.
