Nope, not pregnant, just figuring things out in case I decide to try. So I was just reading on babycenter.com that you are not supposed to sleep on your back after 20 weeks. Well, I've ONLY been able to sleep on my back since about January 2007. I sleep on my back with a pillow under my upper legs and go the whole night like that. So, for you spondy chicks who were pregnant with spondy at some point in your lives, how did you sleep?
