Sir I was engaged in a very high risky sexual encounter after that I go for 4 gen HIV combo tests on 16th day negative 0.10 ,22 day Negative 25 day negative 0.13 and 29 day negative 0.7 between these day I was very stressed and worried I do get some symptoms like muscle ache fatigue and swallon lymph nodes so can they be just a sign of anxiety and worriness I also sleep very less during this period
