Hello! I'm on my 19th week and read I should be sleeping on my left-hand side from now on. I usually do but I do move around during the night - and now I read that I tend to wake up every hour in a panic that I'm in the wrong position and going to kill the baby. And I keep getting leg cramps too! My sleep is terrible as a result and it's driving me a bit mad. So how important is the sleeping on the left-hand side thing? If I find myself sleeping on my back, should I switch immediately? Why does no-one tell you about these things!
