Urine is not clear

I just finished 17 days of Water Fast which was horrible and im gaining all the weight back now.. but what I wanted to ask is 4 days after breaking the fast, my urine became unclear yellow like mixing mustard powder or something! I can see the powder like thing in the urine moving! is this normal and why is it after the fast? urine was completely normal during fast!

I did take my multi vitamins yesterday but ive always taken it and never got this problem.
