Constipation or Kidney stones?

I have been battling constipation since Tuesday, I was finally able to go today with the help of Colace and a small cup of coffee (maybe not as much as I needed but still it was some relief) however, the pain in my side/back hasn’t eased up and I am starting to wonder if it could be kidney stones. It has kept me awake the last two nights, just random bursts of pain just below my ribs on my left side. Does anyone know how to help me differentiate the pains or any suggestions for relief?
