Symptoms if they happen at all, will happen 2-4 weeks after infection, will leave by apx. 2 weeks. Your symptoms are NOT related to HIV. You are correct; symptoms cannot be used for diagnosing HIV, only testing at the appropriate time will tell.
Teak is right. Symptoms will show up at 2-4 wks if they show up at all...some ppl don't even experience symptoms which makes Hiv scarier and more confusing. the doc says that symptoms are never a reliable indicator and that the blood test is the only true answer. I would get tested if I were you to clear up your concerns. goodluck!
