Sorry just a quick post jodie. That same thing happened with me with Lachlan, at 36 weeks and it was my birthday I remember it all so well and was up at the hospital getting my blood pressure checked. I had high blood pressure and I was concerned it may have gone bad as I was exactly how you explained it, like a big divit in your leg that takes forever to go back to normal size and is discoloured (really white/pale). I was told it was just really bad fluid, I am sure it is nothing to worry about. Did they check your blood pressure?
