Potential HIV despite tests, please respond promptly!

I had unprotected sex 23 days ago with a friend of mine. We are both white and 18. She had sexual exposure three weeks before hand. At 15 days I had a DNA PCR and antibody test, both returned negative. She had a rapid finger prick test done at 6 weeks, returned negative. Although it is very unlikely, what is the probability we have HIV. I can stop thinking about it and have developed unnerving floaters in my eyes and blurriness, I hope this is psychological. Plus a dry cough as of day 11 that hasnt gone away and its day 23. Also rash in armpits and spots in various places. I payed 200$ for the PCR but I dont necessarily trust the company i tested with. Is this rational or is my worry unnecessary. Is there still the possibility I have HIV?

What about it. 3 months post exposure is when you can obtain a conclusive negative test result.

how about at 7 weeks with one incident of exposure?

  In an adult, a positive HIV antibody test result means that the person is infected, a person with a negative or inconclusive result may be in the “window for 4 to 6 weeks but occasionally up to 3 months after HIV exposure. Persons at high risk who initially test negative should be retested 3 months after exposure to confirm results

I understand that, however, regardless should I consider her 6 week antibody test conclusive. That and the fact that she has had no Acute infection symptoms.

What part of it is not approved for diagnosing HIV didn't you comprehend?

[daveydave423]

Still if I was undergoing Acute infection, wouldn't it register?

PCR-DNA tests are not approved for diagnostic use in HIV.
