Less baby movement.

Not trying to sound paranoid, just want a comparison. Anyone else notice a decrease in their babies overall movement before delivery? Like I have felt my girl move way less today then normal but I just did my kick counting after a glass of ice water and I got my 10 kicks and then some in the first 20min. I am already at 4cm and 90% and contractions maybe once every couple of hours but so mild I hardly notice them. So I am just curious what some other mommies know and have experience. Thanks for any input!
