I'm kinda worried..

I'm will be 38 weeks tomorrow and I've been having like constant BH contractions for the past three days..not painful..just when I get up to walk around my tummy tightens up..I still feel baby move but barely..she will have little hiccups throughout the day and then like a few good kicks at night when I rest..I'm kinda worried because she isn't moving a lot and it seems like she's always balled and being squeezed really hard throughout the day..should I be worried or is this normal?
