Diaper rash 🤦🏼‍♀️

Can I get like a diaper rash from pads or new panties I just bought? I got the size 5 pads so they go alllllllllllll the way from the front to the back. And now I have like a rash kinda in my butt. Nowhere else just my butt. I’m thinking the pads were irritating it 🤷🏼‍♀️ also just got new panties from Victoria secret that are a silky wired material. So that could be it 🤦🏼‍♀️ but I don’t know I just realized it and I’ve been wearing pads for like 3 weeks because it’s only my 2nd pp period and it’s only spotting every other day. I should have just got panty liners but I was just grabbing to make sure I had some since everyone’s buying everything at the stores. (Yes pads were almost gone at my Walmart) 🤦🏼‍♀️ I got always brand pads
