Baby movement

Brooklynn • Sun, May 22 • 23, married, mom to 2 wonderful boys, Mason and Tristan, and a 3rd boy is due July 9th, 2020.

My son hasn't moved that much today. He pushes his back against my stomach but that's mostly all he's done today as far as movements go and he's done that less than 20x. Should I be concerned or just keep a watch on it?
