I had done protected sex with sex worker. Next day I started feeling weakness. And low fever. With vomits. And next day started with nausea in morning with acidity .which continued for 3 months. I had done hiv tridot test at 15 days and hiv duo combo ag /ab test at 28,56, 70 and last one at 80 days all non reactive. But I still have acidity which causes vomiting some time mrng. Is my hiv test conclusive or I require more testing.
