Suggestions for getting better sleep during pregnancy??

I’m about to be 14 weeks tomorrow, and my OB told me that by 16 weeks I should stop sleeping on my back, as that can prevent blood flow to the baby. But I’m finding it so difficult to sleep on my sides.

Usually I am a side sleeper, but if I try to sleep on my left, my stomach gets really upset now. I’ve been trying to sleep on my right side, but I keep waking up in the middle of the night 1 or 2 times a night because my back hurts and I end up giving up at some point and sleeping on my back.

I bought the momcozy G shaped pregnancy pillow, and I feel like it doesn’t really do much good for me right now as I don’t really have a bump to support. A pillow between the knees helps a little, but I still am waking up at night with my back hurting.

Any suggestions?? I feel like I’m starting to get a lot of headaches from lack of good sleep too (they only go away when I nap). 😭 Would a belly band help maybe??
