kidney stones

I've been accompanied by the worst pain starting off in my hip and towards my lower back resulting in walking being hard and moving around, also frequent urination and I was sick this morning. I've come out with quite a bit of bruising where the pain is aswell so Is this kidney stones? I have dr appointment tomorrow but want to know roughly. At first I thought I was pregnant until I looked into it more, photo attached of bruising. Also, I have flu like symptoms and the shaking chills.  Thanks in advance
