40w and constant inner thigh cramps?

I’m considering going in and getting checked out. I’ve had inner thigh cramps off and on, but tonight they’ve been constant almost rhythmic and moving around isn’t helping them go away as before it would. 😥 I’m 40 weeks today. The pain will also sometimes radiate through my lower belly. Most of the pain is in my legs though. Should I go in? I’m carrying this baby a lot lower, so I’m worried contractions will feel differently
