I'm 30 weeks pregnant and I've noticed that over the last few weeks my baby went from kicking me a lot ( he always kicked low around my bladder/cervix) to basically....no kicking at all! he moves a LOT more now (or maybe I just notice it more) but it feels low near my belly button and it feels like squirming/rolling/moving but no defined kicks. Is this normal? Did he just change positions or something that led to this change?
