*not safe on your back after about sixteen weeks because your uterus is so heavy it can cut off its own blood supply.
Its safe, its not safe on to sleep on your back,, i can't remember why,
Typically okay as long as it's comfortable but I'd start trying to make the change now so you'll have other positions to fall asleep in later on. Don't be too hard on yourself if you end up on your stomach every morning. It's hard to change sleep habits!
