Hi, not sure if this can be answered... anyway, 7 years ago, at uni, I had unprotected sex (I think unprotected) with some random person that only stayed in contact with for a short while after. I am so worried that I may have contracted HIV from this person. I have had an ear infection in past year and problems with my sinuses, although this could be because I smoke and suffer from terrible hayfever. I am a so terribly anxious about this but really frightened to go for a test...help?
