STD, itchiness, paranoia, help!!

Sorry for some potential mild grossness (photo of pubic hair), but as of late my mons pubis (aka fupa) has gotten a little itchy. I think it could be because although I shave around, the hair right on the center have gotten pretty long and might rub against (new) underwear I bought? Plus it's hot.

Buuut as always I've also been paranoid about whether it could be pubic lice? But those you can kind of see so I was looking for some other opinions if there's some stuff crawling about.

Me:

Random photos off of google w/lice that supposed to look like "scabs":

(And yes, today is Saturday so the family doctor is closed, but I'll go next week just for my general STD check up so I'll ask this all then too)

Thank youuu! And sorry for the gross photos 😘😅
