should I be worried?

Armani
My daughter has always been so active but as of 32 weeks, I've noticed hardly any movement. Mayb 10 a day. Their not even hard enough to be noticeable. I can go hrs without feeling anything. I've also woke up in the middle of the night to find out I was sleeping on my back so that has me worried. I'm currently 33 weeks. Is this something to be worried about?
