Hello ladies! I hope you are all staying cool today!

I’m currently 39 weeks today. My tummy is softer than usual, and I get that it’s probably because of her burrowing herself deeper last night (that was fun to stay up all night to), but I am a bit concerned. I feel like I don’t feel her as much. I still feel a tightening in certain places when I drink a cold glass of OJ or eat, but I’m not feeling the big movements. Is it because of where she is hiding? Should I call OB?
