HOLY MOLY

I randomly started getting what I believe may be contractions, starting in my back moving to my stomach. And when the baby moves omg I feel like I'm going to die!!! Are these contractions I tried to take a bath and it hurts to bad I just want to curl up it feels like my ribs are going to explode!!!! I'm 37.4 if that makes a difference!! Can someone tell me if these are contractions? It came literally out of no where and take my breath
