Respected doctors, I was exposed to hiv 44 days back. I took two pills of truvada (day 2 and day 3) and left. I did PCR RNA test and HIV duo test on 15th day which came negative. As I took two pills of truvada I thought there would be some delay for virus to show up in blood so I was not convinced with 15th day test results. On 28th day I did western blot test which came out negative. On 30th day I developed very bad sore throat, mouth ulcers and red dots on arms and shoulder, nausea and giddiness. On 37th day I gave for PCR DNA test which came out negative. Now my parents are cooperating for HIV duo test after 42 days (6 weeks. I am planning to take test after 2 months only. Am I having hiv? Is there a possibility of having a positive result after having two pcr ,1 hiv duo and western blot test negative?
