Can't find a good sleeping position

I'm 15 weeks and the past half a week I've been having a really shitty time trying to sleep. I typically have to lay on my stomach to be able to sleep. But laying on my baby bump is very uncomfortable for me. It feels like just too much pressure so I try to sleep on my side but both sides are uncomfortable. Laying on my back is completely out of the question as I've never ever been able to sleep on my back. Now I've run out of sides to lay on. The only thing that kinda helps is if I lay on my side and have a pillow laying underneath my belly bump. Not sure what to do at this point. I'm already getting up having to pee (which just started. I never had frequent urination in my first trimester) but now I'm tossing and turning all night. Do you think maybe a pregnancy pillow would be something that could help me get comfortable?
