Back pain & sleep

Mattie • Airforce wife ✈ • 🤰🏾🧒🏾 • Due March 2022

I cant sleep, I got shooting pain in my back. I have a pillow between my legs and adjusted my mattress to be less firm (I have a sleep number mattress). My sister gave me her pregnancy pillow but it's so big.

How do u all attempt to sleep comfortably?
