Warm belly button!

Melissa

I’m 35 weeks and today I noticed my belly button and the skin around it is warm to the touch. This didn’t happen with my other two pregnancies so it’s new and weird to me. I’ve already called my doctor and they’re not concerned because there’s no rash or pain with it and my little man is kicking up a storm still. She didn’t have an answer about what it could be. Anyone else have this happen?
