Less movement @ 20 weeks

Hey ladies!
I've been feeling my little guy and he was giving me pretty consistent strong movements and kicks until Saturday. I still feel him mostly when I lay down but still not as active like he was. I would totally be worried if I hadn't felt him at all. I still do but he's just not his normal active kicking self. He's just slowed down. I've read that sometimes this can be a growth spurt. Any other ladies experienced this? I'm ready for him to be wild in there again!
