How's everyone sleeping?

I'm 22 weeks and 2 days. And I can not get confortable on my sides. My hips wake up in the middle of the night because the hurt. Switching sides doesn't do anything I have the pillows between my legs and under my belly. Does anyone sleep on their back with a body pillow to tilt to one side. Is that safe?
