Rash from wearing pad ??

Hello everyone so this is something completely new to me so I’m on my period but my flow wasnt heavy today and I get home and shower and take my pad off when I get out the shower and I have like a rash like between my butt crack and on the front of my vagina like is this normal?? It’s itchy and that’s about it I haven’t scratched it tho because I don’t want it to get worse 😩
