29 weeks back pain and achy

I am almost 29 weeks and my back and sides are sooooo achy. My belly area is too.... is this normal? Assuming it's just everything stretching and moving.

I bought a support wrap, so hoping that helps! Any other suggestions? Help!

I have also been a tad constipated, wondering if it's a combination of both. Does the achy sore feeling go away after a few more weeks?
