Red legs & belly?

I’m 36W5D and I just noticed while standing in the kitchen (Not even 5 minutes long) that my feet and legs are really red. I push on my skin lightly and the white marks appear. This is the same with my belly now. I don’t have swelling or at least not that I notice! Is anyone else having this or know if I should be concerned?

I’m thinking it’s from circulation because I’m really petite with a big belly. But I don’t know if I should call my doctor or not 😬
