Sore pelvic muscles at 39 weeks

Bec. 👨‍👩‍👦 🦘 🍺

I feel like I've ridden a horse or tried some odd flexible sex position because my pelvic muscles are aching.

I understand that the pelvis expands to make way for the baby and therefore it uses muscles not often used but I didnt think I'd be walking around my house bow legged.

It is more predominate after I have been shopping (so a few hours of walking)

Anyone else had this and can offer a solution?

I might just revert to laying on the sofa all day.
