Help advice !!

I did oral with a guy the beginning of June and after he had told me he had been tested up until the girl he hooked up with before me he used a condom with her but ate her out and I think she blew him too not sure so I felt fine then got my period July 6th it was pretty normal then right after my period I started having redness and pain slight itchiness down there it almost feels dry or swollen Raw feeling I finally went to the doctor but he said everything looked normal inside and he wasn’t concerned with the redness because I sweat a lot at work and just to keep the area dry and all my blood work came back normal so I’m clear of those STDs but I’m still waiting on the rest that we’re swabbed should I be worried ??
