Hi! Am vry much worried that I may be infected with hiv because i've had a sexual relationship with a girl whom I didn't know. I've had hiv test in 3 weeks, 3months and 6 months respectively after that sexual act. All the 3 tests were negative and am not having any symptoms as those of hiv. The girl also had herself tested and she was also found negative, but am still worried, I don't know why, may be because am getting married in 2 month. Often ther is a question that crops up in my mind that, may be there is a new type of virus of which am infected with n that's why my tests were negative. Is that thought of mine possible? How are new type of hiv virus discovered? Please :(
