19 weeks and pain?

So im currently 19 weeks and 2 days and this baby boy of mine is my 3rd baby😍

With both of my previous pregnancies i felt my babies move pretty early, especially my 2nd(my only daughter). They both started off with gentle little flutters.

But THIS BOY!!!!! I didnt start feeling him move until at LEAST 17 weeks. And for the past week he has been moving so hard it hurts!(mostly anywhere near my hip) How can it hurt so bad if hes so small!?!?! Is my uterus just sensitive this time around? Ive never really felt pain when my older 2 would move, especially at 19 weeks🤨

I have a feeling this is going to be a rough ride 😬... or hes gunna be a big boy😞
