HIV/AIDS Community

Last Friday on 11/2/12 I engaged in a sexual encounter with a transsexual prostitute. The details are as follows. We had multiple deep kissing sessions, we performed unprotected oral sex on each other, and we had protected anal sex where I was inserting. He said that he is clean, was last tested in September, and has no visible symptoms of HIV. I also found that he had no visible symptoms when we were together, I did not see a rash, warts, sores, or the like. There was no blood at any time during our encounter. He did finish himself on his stomach and I did not touch his semen. We used a lubricant to help with the anal penetration, and several times, I spit in my hand to add some lubrication. When it was time for me to finish, I removed the condom and finished with my hand, the same hand that I spit into. It looked as if some of the lubricant naturally escaped on to the sheet. But I am confident that I did not come into contact with any blood, semen, or pre-cum. The only thing, as noted, would be the potential for anal secretions as noted on my hand, during masturbation.
For the first few days, roughly until Wednesday, nothing happened to me. But around that time, I really started to worry about the possible contraction of HIV. So I started reading about the symptoms non-stop, every site possible. I went out and bought an OraQucik test (which was negative, but means nothing). Thursday, I started to develop lower back pain, which I suffer from often. I ordered a HIV RNA test for Monday (11/12/12). Throughout this past week, I have been taking my temperature, and it was good until today (Friday). When I got home from work on Friday at 2:45 pm it was 99.2. In a rush, I went to the ER to see what they had to say. I recounted what I have written here, and the doctor said I have nothing to worry about. They took a urine sample for STD testing, and asked me to follow up with the clinic that I go to for the HIV RNA test this Monday. Friday my temperature is 99.5, and I have chills, which come and go. I cough a little bit, but it's more of a clean one's throat attempt.
At around 2:30 Saturday morning, I awoke and took my temperature and it was 100.5. I had a very slight headache (which I posit might be the side effect of the trazadone, as seen below).
I am so incredibly worried and anxious. I took trazadone (50 mg) several times on Friday (which I normally take for insomnia). I am obviously showing signs of stress, like morning gagging, and loss of appetite. On Saturday at 5 pm, my temperature is around 100, plus or minus a few degrees, after taking some DayQuil.
When waking Sunday morning, I had a fever 101.5, and taking medication reduces it to 99.9 +/- a few degrees. At the moment, I really do not have any other symptoms, not really coughing, I had some aches this morning, but they went away. So obviously my fever has been increasing since Friday.
So I guess my question is, have I worried myself sick? Has my stress precipitated this fever with little symptoms? It has been cold the past week, and I walk to work in the cold, and take public transportation as well, so I suppose it can be a flu or cold. But is this either this is an amazing coincidence or do I really have something to worry about?
Additionally, what is, statistically, the earliest one can get tested using an RNA test. As noted, I have one scheduled for 10 days after an encounter. Thoughts? Recommendations? Should I trust the result? I will also get the antibody test at 3 weeks.
