What is this?? Dry red spot

Tina

I've had this spot on my upper thigh (almost my hip) for a good couple of weeks now. It's about the size of a chickpea and the skin flakes all over it. I've had dry spots before but after putting lotion on, they go away. This one wont go away with anything that I've tried. Anyone have any insight?

Also, I'm 24 weeks pregnant if that means anything.
