Baby’s movement?

I’ve been feeling movement since week 15. I’m almost 19 weeks now and the movement had been a lot more intense and frequent recently. Is that normal? I know doctors emphasis the importance of paying attention to baby’s movement? This is my son when he pops himself out, I’ll lay down and my belly goes down but he comes up! 😍 ( also, I have lotion on the stomach in the picture and ignore my chest, my ribs are in-caved in the middle 😂)
