37 weeks reduced fetal movement. Should I go in to get checked?

I'm 37+4 today, woke up this morning and felt a little kick and that was it. It's now been 6 hours, I ate a big breakfast, had a doughnut as well, and a cup of coffee. Usually he's moving like crazy by this point especially after I eat, yet I still felt maybe one movement over the span of an hour.

Decided to head home and grab our hospital bag to go in for NST and as we got home he decided he wanted to move a bit. Got 10 kicks in the span of 30 minutes, but that was it. Nothing in addition to those 10 kicks and usually he moves quite a bit.

I'm really worried should I go get checked out?

UPDATE: I just spoke to my OB and explained my concerns, she said it's good I was able to get a solid kick count about an hour ago and to continue to monitor him throughout the day. She also said if he continues to have long stretches in between kicks to call back and they'll have me come in for a NST
