Baby movement worries

Inessa • I'm 26 years old , I'm currently self employed, I am married to an amazing man! We have a beautiful baby girl that was born under a pound. At 26 weeks , I am currently pregnant with baby number 2 ♡
I've been feeling my baby flutters since 11 weeks this is my second pregnancy. This past week I haven't felt my baby kick i am 15 weeks now, should I be worried? Call the doc not sure what's going on, anyone else?
