my last risky encounter was in the mid Feb. i have been underlots of stress ever since even though it was protected. 20weeks post expousure i could'nt stand it and went to my doctor and told him about it. he told me that i should'nt worry becuase i was protected but i insisted on having and hiv test and i got a no reactive result. when i asked him about hip c he told me to not worry about it becuase i was protected and that it is rarelky transmited sexually nd that i shouldn't think about it. my question is how true is that hip c is rarely treansmited sexually? and would hiv or hip c trigger an autoamunme disees in 20 weeks post expousre that would ulter my hiv test results ( my test was an ELISA in one on the biggest hospitals in the city i live in)? and what does no reactive mean when it comes to hiv testing?
