I had a protected sex with a prostitute on 26th December 2021, today is 17th January 2022. I am confused about symptoms though as I'm reading everyday on internet due to stress. I had tested myself for hiv by 4th generation ab/ag & p24 on 10th day from the potential exposure and the result was non reactive with index value of 0.12. Is it conclusive that I don't have HIV or I have to take another test on 28th day as suggested by my doctor,  post which I can be sure I'm not having HIV infection if tested negative, please suggest. My doctor said if you are tested negative on 28th day then forget about it and move on. I'm confused please help.
