Trouble sleeping

I'm 20 weeks and not sleeping at all. When I do fall asleep on either my left or right side my hips hurt so bad I wake soon after dropping off. Aswell as going to the loo 4 times a night I'm struggling to find a comfortable position.

I have a wedge for my tummy and a full length pregnancy pillow but neither seem to help. I have slept on the couch sitting up a few times but that's not sustainable.

Any tips or help would be greatly appreciated
