HELP!

Raegan • mommy to a 33 weeker ❥ riley kate ↠ 06.26.16 and though she be but little, she is fierce.
I haven't felt Riley move since about 9-10 this morning and still nothing. I've drank cold water, and even poked her for about 30 minutes to try and get her to move. Should I be worried? I mean I already am, but just need to know if I should call my doctor.
