Hi I Had Unprotected Oral Sex And Protected Sex With

Hi I had unprotected oral sex and protected sex with a man a week ago. After 2-3 days I had tonsillitis like symptoms , no real fever ( only mild) and not too much of a sore throat. I got some penicillin antibiotics and have had a rash ever since ( day three of rash now and one week after sex) I think I may have been exposed to hiv even though i have not had a bad fever and flu like symptoms etc... Thoughts?
