Since my fundo, I've experienced the gambut of colors and consistencies. Not to worry. Your GI tract was rearranged in a big way. I'm still experiencing a wide variety...I'm sure it's very common--especially if you have a reactive stomach--which I do. This too will pass, so to speak!
Glad you got to take a shower. That is definitely a treat. The not eating will pay off in a big way, once you're all healed.
Take care of yourself.
