i had unprotected oral and vaginal sex from a female about 4 months ago, and just recently started having the symptoms of hiv. first it was a chesty cough, then strain like headaches all the time. about a week later i noticed my tongue was white and i had some white sludge on the very back of my tongue that would scrape off. all of these symptoms point toward hiv. i got a test done and it came back negative, i know i sound paranoid but would just like an explanation.should i get another test when a year comes up? thanks for your time.
