Low sitting baby

Kristi • I'm a stay at home mom to a little boy who's 2 years old. I'm currently pregnant with my second who is due 10/17/16.
Any one else's baby sit really low in their pelvis? 24 weeks + 1 day and my son usually sits low but today he's really in my pelvis. Everytime he moves hes like kicking against my pelvic bone it feels like he's coming out lol. It's such a strange feeling!
