side sleeping?

Beth
So I know that in the second and third trimesters we aren't supposed to sleep on our backs....but I am finding myself waking up on my back several times a night. OR when I wake up on my side my hands are completely asleep. This morning I'm finding myself with shoulder pains. Is anyone else dealing with this? Any solutions? I do have a pregnancy pillow but is not seeming to do anything but add another pillow to our bed....
