Red Rash on belly??

Caitlynn
I've had this little red rash looking thing on the top of my belly for awhile now. I thought it was from my bra but haven't worn one for a week or so and is still here. It's dry to the touch but is not noticeable at all unless I look for it, not itchy and doesn't hurt. Is it normal, from the hormones or should I ask my Dr about it?
