I'm just about 31 weeks and it feels like my son is lodged in my right rib cage. I can't tell if it's his foot or what but it sure does hurt😔 I'm not trying to complain, I feel so blessed for my baby. This is my first pregnancy and it's all new to me.

Is their anything I can do to relieve the pain a little? Right now I'm laying down on my right side. Any advice/suggestions?

Thanks mommies☺️
