2 weeks ago I had protected sex and unprotected oral sex, I think after a week exposure I went and got tested For everything , I know to soon for HIV but everything was negative and nurse said she didn’t see any elevated white blood cells.. for the last 3 days I have been experiencing on and off bad headaches and feeling like I’m going to throw up.. what’s my chances of getting hiv because now this is going through my head that I might have picked this up
