Almost 23 weeks. Investing in a pregnancy pillow? Worth it or not?

En

Hello, I have the wedge pillow that I can tuck in under my tummy. That works during the previous weeks. But lately, I’m having a hard time. I felt like I need more support specially my back and my legs. Any good recommendation that you tried it to yourself?

Which one to get? The U shape or C shape? I don’t wanna sleep on my back. My leg and pelvic area hurts too when I sleep on my left side. I just wanna be comfortable sleeping on my left side.
