Hello Tom
Although HIV can be isolated typically in low titers from saliva of a small proportion of infected individuals , there is no convincing evidence that saliva can transmit HIV infection either through kissing or oral sex ( so in your case HIV rule out with this way).
Antibodies to HIV begin to appear within 2 weeks of infection ( so this is also ruled out that you are having HIV infection ) but in your case you tested 2 months after contract .
You are having headache ,
body ache but these symptoms may be due to stress or trauma , so need not to worry .
Symptoms of HIV are , fever,
pharyngitis ,
lymphadenopathy, headache / retro-orbital pain, arthralgias/myalgias, lethargy/malaise, anorexia/
weight loss, nausea/vomiting/diarrhea , rashes , Mucocutaneous ulceration ( on tongue and in mouth).
None of these symptoms present in your case , so no chance of HIV infection.
Still you have any doubt get P 24 rapid nucleic acid amplification test for confirmation . But in my opinion according to your query , you are HIV free.
Good luck.
