I'm 28 weeks pregnant and as recommended have been sleeping on my side (left side as much as possible). The last few nights I've been woken up every hour or so with pain in the hip I've been laying on and had to switch sides for another hours sleep before the pain in the other hip wakes me up again. I did have this a few weeks ago and I've been sleeping with a pillow between my legs which seemed to help. But now even with the pillow the pain is back. Any other suggestions?
