Discomfort While Sleeping

I’m about 10.5 weeks along, and while I’m not really showing, I’m having such a difficult time getting into a comfortable position while sleeping. I’m typically a back sleeper, but have been sleeping on my side because it no longer feels comfortable- similarly, when sleeping on my sides, it feels like I need one of those pregnancy pillows between my legs and under my head, because these positions also feel uncomfortable. This is probably affected by slight nausea, indigestion, obviously insomnia, all other symptoms - but just wondering if anyone else is feeling this way, and for anyone who has children, when/if you purchased the pillow?
