I've read that you should start sleeping on your side (preferably left-side) by the 2nd trimester. I'm a back sleeper with different injuries that just makes sleeping on my sides pretty uncomfortable. Bought a Snoogle, but inevitably, I still end up tossing the Snoogle off the bed and end up on my back sometime in the night. Going to ask my OB next week, but when is it really imperative to sleep on your side?
Did you sleep on your back or have trouble staying sleeping on your side?
