Herpes?

I have a doctor's appt on Monday, I have had a cluster of pimples (just red, no whiteheads) like on the corner/under my lips for like a month now. I'm starting to freak out and my appt is Monday, so I know I'll be taken care of soon - posting to see if anyone has any knowledge on this beforehand? every Google search I have done is unrealistic and pulls up terrifying images
