My belly stops me rolling onto my belly LOL
I do sleep on my side, mostly my right but I have been making a concerted effort to sleep on my left to help baby move from back to back
I can't wait to sleep on my tummy again.
I keep trying to sleep on my left side as I read all the time that it's best position BUT I can't breath properly when I do so have to sleep on right side. Saying that I end up turning like a pig on a spit all night long cos hips get sore. Pregnancy really knows how to make us happy!!!! lol
