FTM question!

I feel like this is probably asked often. I am fairly certain I posted about it recently in a way. But when having actual contractions, can the pain start from the back move to the hips/upper thighs and then to the lower abdomen? Or is that BH contractions? I know when I had BH the other day it was just tightening of my belly, no pain in my back or hips. I am trying to lay on my side and drink water to see if that helps. That is what I was told to try two weeks ago.
