Pre clampsia?

Hi ladies, 
I'm 35+3 Since Thursday I've been having really bad pains under my ribs on the right side and my stomach is completely hard there, and since last night I've had a migraine that I am struggling to even open my eyes with and I'm loosing my balance when I walk because of it.. Does anyone think this could be pre clampsia and I should go and get it checked out or is this just normal?
