Painful lower tummy skin in pregnancy

I tried looking anything up on this and thought I’d just ask on here if any other woman experience this.

The area above my belly button (all of the skin) feels soft and normal.... the skin below my belly button all feels rough almost like there is a layer under the skin that feels glued together or something?? It has ridges on it that feel like very hard veins but there is NOTHING visual from the outside. It is all just feeling. Any advice?
