Don't worry. Sometimes it takes 2 or 3 flushes for the stones to come out. For my first flush, i didn't get any stones. It's probably lodge in there pretty tightly so it might take a couple of more flushes to loosing it up. It's important to remember to clean the bowels afterwards cause you don't want the toxins to recirculate back into your system. I recommend doing colonic afterwards in conjunction with liver flushing. That combo thoroughly cleans you out. Good luck with your flushing!
