Punched in the stomach at work

I am 31w3d today and am a daycare teacher. While working today, one of the kids (4-5yr old) punched me in the stomach so hard I puked. My baby has been moving really well, I’ve felt 10 kicks in the last hour, but I’ve been having some cramping. The cramps are kind of stabby and they are below my belly button on the left side. Should I go to L&D to have him checked out or are these cramps considered normal? I’m just not sure where he’s moving a lot if the cramps are something to be concerned about or not
