I agree with FWM - get as many pillows as you can and experiment with them until you get it right for you.

I too sleep on my tummy and struggled with it, but I found I could sleep at a kind of three quarter angle, not quite on my side and not quite on my tummy (obviously) with the help of pillows etc for support.

If it's any consolation, it does help train you into having disturbed nights when you have the baby, and you'll probably get more sleep after he/she arrives than you did in the last few weeks of your pregnancy!
