I went through the same with my first pregnancy. I slept in my recliner the whole time..i got the best sleep that way
I just found out that I am 9 weeks today and I never can get comfortable either. I lay on top of a boppy pillow so my belly has room but I am a stomach sleeper so it's not easy.
Yes I have tried that hubby even bought me a body pillow I just can't get comfy unless I'm sitting up so I've been sleeping in the recliner
Have you tried sleeping on your side with a pillow or cushion in between your knees/thighs? That helps me get to sleep
