I had an HIV PCR test the 28th day after potential exposure. The woman I was with is a co-worker who is married and swears she has never had other partners nor has her husband but I am having all kinds of symptoms. I am also married with children and much to risk. I know I am so stupid, the guilt is unreal. My question is, I have had soar throat, swollen lymph nodes, stomach aches and headaches non-stop. My question is, are the results to the PCR test reliable? I don't want to harm my wife. Do I need additional testing if the results come back negative. Thank you for your help.
