Decreased movement??

I am 30 weeks exactly today & usually my little girl is pretty active during the day. I just realized that I haven't felt her move much since I was on my way to work at around 7:15/7:30 this morning. Is this something to be worried about? Should I call my OB? FTM & kinda worrying. 😩
