HIV exposure, high risk

[guyworried1982]

On 3/28 I had made the dumbest decision of my life and now I'm worried sick. I had anal unprotected sex with someone that later told me he was HIV positive after he got tested. He said his event occurred sometime in December of 2013. So I went to get tested at my doctors office which was a HIV 1/2 O test which was on 4/7. While waiting on the results I took a oraquick test which came out negative about 4 days giving my blood. Then I got the results which they said was not positive or negative which put me into automatically thinking I'm positive mode. The doctor now wants to do a RNA test. Two weeks later I tested again with oraquick which was negative (4 1/2 weeks after exposure). The next day I devloped a cold with no fever(I constantly monitored that) only had sore throat , runny nose and coughing which lasted only about a week. Today I'm feeling like something or pressure on the right side of my jaw and neck. I have no idea what swallen lymph nodes feel like  or look like but every time I swallow I feel this pressure there. I don't feel anything swallen or anything while touching it with my hand. I diffently feel it and its not in my head.

Giving all this information  got a few questions:
1. Why did my other std test came back negative except hiv? Which came back "not positive or not negative"
2.why did the doctor order a RNA test instead of doing another antibody test if the antibody test failed? What is a RNA test?
3. At 5 weeks how good is oraquick at detecting HIV antibody's?
4. If I'm infected does having symptoms mean you have antibody's? Or when does antibody's actually start becoming active?
5. How come I'm not getting the same result that I got at the doctors office on oraquick?

Sorry for all the questions and I know this is probably commonly asked but this looks like a good place for help.

how often does results from the doctors office come in like this? i mean intermediate? also since i was potentially exposed could i have the antibody's but not be infected?

one more, what does swollen nodes feel like? i mean i have this pressure feeling going from underneath my right jaw to my ear(internally) I don't feel any bumps on my neck or abnormality to it just my neck. with your hands does it feel like bumps or something?

1. It may not be necessary that an HIV+ person also has other STD's as well or vice versa
2.If your test was indeterminate (neither negative not positive) the best thing would be to repeat it, however I can not comment on what your doctor has said
3. At 5 weeks, an oraquick test is reassuring but not conclusive, which must be at 3 months mark
3. No ! Symptoms have nothing to do with antibody presence. Many actually infected people remain totally asymptomatic, and likewise, many experiencing almost each and every symptom, turn out to be negative at the end of the day
4. Ideally the results should be the same, regardless of the method adopted. When we talk about HIV testing, window period is important. The test may be "false negative" if done too early
