HELP ! I’m scared

so i had sex then 3 days later i had a small open sore appear and it had gotten bigger !!! i hope its not herpes but i fear it is and my heart keeps racing ! i went to a dr who did a swab and a hiv test and syphillis test and all came back negative comes to find out he didnt do a herpes swab test it was a regular bacteria test cause he thought maybe i had a skin infection !! he prescribe me azithomycin but it only helped so much i still have this lesion which is still very raw and when i pee it kind of burns when it hits the sore and i have a bit of discharge but not smelly .. i went to another dr who testing me for herpes , says it doesnt look like it but just to test in case , !.jpg)
