Oral sti testing help urgent please!!!

Hi I’m really nervous that I have an oral std or sti and I was wondering if anyone knew where I could get an oral swab test done without my parents finding out in any way- I can pay out of pocket but I am really nervous about potentially having an sti or std and I want to get tested as as possible. Also can someone explain how planned parenthood works for this kind of testing? Do you have to go through insurance? The planned Parenthood near me is quite far so if there are alternative options that Will keep my info and results confidential so my parents don’t find out That would be ideal for me. Thank you for your help it means a lot to me
