Red rash under belly button

Ni2 ❤

I am 8w4d today. As usual early morning I got up to pee and I noticed a mild pain under belly when checked in the mirror I could see red rash like I have scratched myself but I dont remember doing anything. could this be the "expected" rash? I have been having a heated itchy rash on both ears for some days and now this. what could be causing this? does anyone else experienced the same?
