Anterior placenta

I’m 33+1 and i feel like I’m starting to feel less kicks towards the front of my belly and I feel them mostly when I lay on my side. So when I do kick counts I lay on my side and I always get to 10. But if I’m sitting up I don’t feel much. I have an anterior placenta. Is it normal to feel less movement towards the front of my belly the farther along I’m getting?? Because my placenta is getting bigger so more cushion maybe??
