Back sleepers?

Do I have any other fellow back sleepers due in December. I have been trying so hard to adjust how I normally sleep, but I wake up on my back every time I get up to pee. I just purchased a pregnancy pillow but it won’t be here til next week. Just looking for some reassurance that I’m not the only one!
