I have a rash after wearing period pad but im scared it's herpes. Thanks Google

I am 42 years old.. I have a steady partner. I usually shave but last time I shaved I cut myself so I decided to give myself a break this month. I had my period and now I have a weird rash after wearing panty liners. I do get cold sores on my lip and I keep looking for pictures online of what herpes looks like bc i’m worried I may have transferred the virus to my genitals at some point. I felt a tingle in my lip this week but nothing came of it. Except this..does this look like herpes? I shaved the area for better visibility.
