Is this herpes ( pics included) HELPPPP!!!

ive been having raw sex with this guy for about 7 months. i got tested on september 21,2020 and my blood and culture results were negative for STD's , BV, yeast etc. we recently had sex again on october 5th and everything was fine until a few days ago i noticed this lesion sorta thing on the outer lips of my vagina. ive never had this before and im freaking out !!!! ive also just started using new tampons a week ago when my period started and noticed it started around that time. could it be herpes or the new tampons? HELPPPP!!! there is no pain or anything or itching really and i havent had any flu like sypmtons
