Having trouble sleeping?

I'm 8 weeks pregnant now and haven't been able to sleep in our bed. I have to sleep propped up with pillows on our couch. I usually sleep on my back but since you can't do that in pregnancy, it's been so hard sleeping. I have a curved lower spine, so sleeping on my sides isnt restful - I usually have stomach issues and pain. I tried one of those long curved pregnancy pillows but it stressed me out trying to sleep with it lol. Is anyone else having trouble sleeping and can't sleep in their own bed?!
