Feeling baby move in pelvic area🤔

I'm 31 weeks & 5 days.

Every time I feel my son move, it's really low and a lot of times right in my pelvic area? I've always felt him move really low, but I kind of thought I'd feel him move a little higher than this by now, with him growing and getting bigger?

I never really thought anything of it until now, since I am feeling him lol just curious as to if it's normal to always feel them move so low sometimes or if I should ask my doctor about it.
