Sore/Heavy feeling

I’m 37 weeks and since this morning have had this super sore ache feeling on my lower stomach, I know baby is low and down already but I don’t remember feeling this way with my first. It feels like I did insane workout and pulled something but not in a typical place, almost as if like I had surgery or something? Hard to explain, is this normal toward the end or a possible sign labor is close? When I pee or bend/squat I feel like he’s gonna fall right out and when I walk it just feels super sore under my bump but above my vagina if that makes sense.
