Still no movement...

Amber • 25, married to my best friend, and mommy to two amazing little boys! 💙💙
I am 16 weeks 5 days with baby #2, and I have yet to feel any movement. I feel like I was already feeling the butterflies with my first. I'm not sure why, but I have been extremely nervous this whole pregnancy, like something is going to go wrong. If I could feel movement, it would at least give me some reassurance. 
At almost 17 weeks, shouldn't I be feeling the baby move?
