Tell or Say please, whether it is possible to lay longly on a back on 31 33 weeks of pregnancy? Heard what to sleep better on left to a side, but I all time wake up on a back. It is not dangerous?

No, not dangerously, but it is better to sleep edgewise because on a back the bottom vena cava can be pressed and be at a loss outflow of a blood from legs or foots, that at vstavanii (especially sharp) can lead to a syncope.
