Hello Mr. Rajesh
Unnecessarily , you are worrying.
Almost 3 months passed after sexual act.
Tridot test is NEGATIVE.
You don't develop any symptoms , which indicates that you are having HIV infection .
For your information and satisfaction I am writing symptoms ( earliest ) of HIV infected person.
Fever,
pharyngitis (
common cold was there before sex , so not a cause of concern ) ,
lymphadenopathy, headache/retroorbital pain ( behind eyes ) , arthralgias/myalgias, anorexia/loss of weight, nausea/vomiting/
diarrhea.
Erythematous
maculopapular rash, mucocutaneous ulceration ( tongue and in mouth).
You are NOT having any of these symptoms , so no chance of any HIV infection.
Still , you are in dilemma , so get in nucleic acid amplification ( PCR , RNA ) test for HIV confirmation.
Good luck.
