If it's your hips that's bothering you, have you tried to put the body pillow between your legs? That's what helped me when I was pregnant with my son. I sleep more often with one leg bent and the other straight so what I do is sleep with my bent leg on top of the body pillow and just keep the other straight like normal. It seemed to help keep my hips in line and they seemed to hurt less. When I was pregnant with my son at one point, when hubby wasn't home (he worked nights), I had two pillows one on each side so if I switched sides I had a pillow at the ready. LOL This time I'm trying to do the same...but it doesn't always work; some nights I sleep better than others.
