Sleeping sucks

I don't know about anyone else but one of the hardest parts of being pregnant, especially being fairly early on (12 wks) is not being able to sleep on my back. I didn't think I was normally a back sleeper, but not that I'm not able to, I'm realizing how much I really sleep on my back. I thought adjusting from sleeping on my stomach would be hard, no way. Figuring out how to not lay on my back is way worse!!! Any tips or comments??
