I am a 23 yr old male and about 6 months ago I had sex with a high risk female. I was under the influence and do not remember the details of what happened. I for the past 6 months I have been worried about HIV. I have had some different kinds of mouth sores, as well as sore thoat, diarhea, and occasional swollen lymph nodes. I have had negative test results at 2 months and 6 months, but I am curious as to how conclusive these results are. My symptoms continue to persist and though I still don't know what I have, but I'm very confident I got it from the aformentioned female because symptoms began to show up a few days later. Do I have anything to worry about???
