Hiv testing accuracy?

I've had three antibody negative test results between 3 and 6months from exposure. I've had flu like symptoms on and off for 3months as well so that is why i continued testing. At one point when i felt very ill (swollen glands,sore throat, headaches,etc.)(3months post exposure) I took the dna pcr qualitative test and that came back negative. My question to those with knowledge or experience with this is as follows: A. With traditional clinical symptoms shouldnt one of my Antibody tests be positive if I was infected by HIV? B. With the DNA PCR test(post 3months exposure) and having symptoms of a viral illness shouldn't this test pic up the viral activity if the illness is HIV caused? Just trying to rule out this disease and thanks for the feedback!
