Reduced movement?🤷🏻‍♀️😕

I’m 39 weeks tomorrow and today I feel like the baby hasn’t moved a lot? iv felt him push out his back or bum probably about twice today but that’s it? he normally moves a lot more then this and it’s worrying me, the last week or so he keeps staying to the left side so I don’t know if it’s just the position he’s in or what but should I ring the hospital just in case or is this normal? Thank you.
