I'm 28 weeks and my pelvic area has been sore for weeks! It's from everything stretching, moving around, since you're practically almost to your due date I'm sure your baby is already on breaching position! Sleep with a pillow between your legs. And keep your knees together when rolling over or getting out of bed!
Yea I went through that. So not fun. But now it's this weird clicking noise. It doesn't hurt, just different. I'm going to try and keep my knees together when rolling over. Maybe that will help with my hips.
