Is this herpes or something else?! plz very nervous

Today after a long shift (i wear tight leggings for work) I noticed a little itchy red mark on my buttock area. Its not blistered or raised, no puss. But ive never had anything like this. Anyone have any idea what this could be? It looks like a little scab or flakey skin but im nervous it could be herpes… pls lmk!

heres another photo! Its been itchy for the past few hours but no sign of blistering. Its very small but i know HSV can come in all shapes and sizes. I have an appointment with my gyno soon but Id still like to hear from this community! image
