I would not consult any doctors and do the flush right away. Then I would start parasite clense and do another flush... It is a long way and all you need is just to start it. You will love it!
Those object that you pass seem like gall stones to me.
I have done 12 flushes already. I did not have any of your symptoms or any problems or pains in my liver area ever, I was just eager to do the flush after my frinds introduced me to it. I passed loads and loads of gall stones. Small and huge ones and feel much better even though I was quite sure that my health was in very good condition.
Do the flushes while you don't feel any pain! And you will see everything by your self.
