Back pain from left side sleeping

Just sharing what I’d read. Hope it’s helpful. https://www.healthhub.sg/live-healthy/1710/4-ways-to-get-comfortable-while-sleeping And I bought a wedge pillow for support. It takes less space than the u shape pillow. Even if I turn it’s at least 30 degrees elevated. But may be need to change to u shape when the belly gets bigger. But depends on individual. My friend bought all the pillow but she still prefer using normal pillow as she can adjust where she likes to put.
