Concerned about lack of movement

Emily

I’m 30 weeks with my second. He’s usually pretty active all day, but today I was on my feet a lot and really just busy. Well finally had some down time the last few hours and I haven’t felt his regular movements, like very light kicking if anything. So I sat with my feet up, and drinking water. I started having cramps and running back and forth to the bathroom feeling like I had to have a bowl movement. I have GF but I thought maybe if I had some ice cream he’d move more, but no I’ve only felt a kick once or twice. Should I go in to be seen? Or is he just having down time... never felt this way with my first pregnancy
