Fever is characteristic of HIV infection. That you don't have it is good. Rashes can occur because of stress and so can some of your other symptoms. The description is not a typical ARS rash. The mouth with all its enzymes and saliva is extremely hostile environment and HIV is a weak virus. So that's on your side.
The best thing to do is get a 4th generation HIV test from your doctor. At 4 weeks after the incidence. A negative at 4 weeks with 4th generation is considered conclusive.
First, your exposure was no risk. You can't be sure what you tasted was blood, and even if you did, saliva neutralizes HIV. So, in the highly unlikely event this girl was HIV+ (you don't know for sure, I don't care what you "feel"), you were NOT at risk of acquiring HIV. Second, "symptoms" are never used to diagnose HIV, which is impossible in your case considering your exposure would NOT have resulted in an infection.
