Having trouble not laying on your back?

michellerupp

I asked my doctor about laying on my back because I had read that doing so for a prolonged period of time could be harmful to both mommy and baby because of the risk of cutting off blood supply.

I often wake up in the middle of the night on my back, even though I fell asleep on my left side. 

I've also been having some upper back pain, which usually only subsides when I lay on my back with a heating pad. 

At my last appointment (almost 25 weeks) I asked my doctor about laying on my back and she simply said " do what makes you comfortable and don't worry about it." 

Thoughts?
