Sleeping issues

I'm 31 weeks along, and me and my boyfriend are having some issues with sleeping arrangements. We like to sleep cuddled together, but with my arthritis and the extra weight, I'm now to the point that I wake up every 15 minutes or so with pain in my hip, and have to roll over onto my other side. With us sleeping so close, my rolling over wakes him up, and we both end up having to spend 5 minutes or so re situating ourselves to get back to sleep. After that, there's only a little bit of time before my other hip starts hurting and I have to flip over again. We repeat this all night. Anyone go through anything similar and/or have any suggestions?
