Decreased movements 34 weeks

Ja

Hey ladies I don’t know if I should be paranoid but my baby is usually hyper n all over the place. Just yesterday he was moving so much. I can usually see him poking out my stomach. But today I’ve been a little worried because he hasn’t been moving like he does. I tried drinking cold water and counting kick but it’s extremely decreased. At first I figured he was sleeping waited a good 4 hrs and checked again and still not even 10 kicks in a hour. I’ve always feared him wrapping his umbilical cord around his neck since he moves soooo much since I was 13 weeks. What should I do? I just turned 34 weeks yesterday. Should I go get checked out. How would they check if he’s okay in there .
