Have you tried pregnancy pillow? I started have some back pain since wk 9. Decided to buy a pregnancy pillow that helps support the back while side sleeping because sleeping on the back is not recommended. It really helps ease the back pain and I’m able to sleep well with it.
it's normal.. try sleeping on your left for better blood flow to your baby too.. when baby grow bigger, try to avoid sleeping on your back..
yes it’s normal but should avoid sleeping on your back from now on
