Vulva peeling

So a couple days ago I started my period and I was wearing a panty liner because my period was not as heavy but I started to notice that I started to like feel irritated and when I checked the outside of my vulva was peeling and I didn’t really pay much attention to it so I kept wearing panty liners and then I noticed that my skin was really irritated and it look like I burned myself down there so I don’t know if it’s an infection or it’s just really irritated. It looks like a diaper rash. I don’t know what to do.
