Back pain anybody?

JA`s Mommy👶💙
So I'm 38w3d and just so ready to have my baby boy. So I read online that dancing can give labor a jump start. So as silly as it felt I started dancing lol? Anyways a few hours later my middle part of my back started to hurt and is still hurting today. Can this be a sign on labor or did I just hurt myself while dancing?
