Baby kicks at 28weeks?

So I'm 28 weeks pregnant, with my 3rd and I don't know whether it's because my previous baby was only 18 months ago that I remember it so well , but I feel like this baby never moves, I don't ever feel strong kicks. My placenta is at the front this time as previous one it was at the back so I'm assuming that would make a huge difference. It's so weird , I remember after I ate I'd feel so much movement in my last one..this one I feel next to nothing. I used to be able to poke my belly and make the baby move, this time I can't. I'm just finding this really weird and I'm really longing for some connection with the movements. Anyone else been like this? Or should I go get checked?
