I think I have HIV

I’ve had unprotected sex a couples Times with a guy that I know has had sex with other girls. I randomly thought one day to myself “what if I have hiv” and after that day I have not been able to get it out of my head. I’ve been so nervous and anxious. I’m 17. Should I go to a planned parenthood and get tested? I’ve read if I catch it now I can live a regularly normal life. I’m just very scared. I do have some of the symptoms they say people get but sometimes I wonder if it’s just my head making them up.
