Less movement with baby

I'm 30+2 today and the last few days my baby has been moving around. Usually he kicks loads when I'm hungry and then moves around slowly after eating and kicks randomly throughout the day

Today though he was kicking only a bit and I'm hungry and he isn't really budging, I literally get the odd movement and that is it.

Should I be concerned ? I was pressing and moving my belly around earlier and he did a powerful kick back then turned around.

Please give your advise as this is my first pregnancy so I don't know if this is something to be concerned about
