second liver flush and ?

Hi! I did my second Liver-Flush last night.I was pleased with my results,except for the burning water.I have been passing red water though and am concerned.I have not had any pain or discomfort.I did feel pretty drained earlier today but feel like myself now.Has anyone ever noticed red water during/after a flush?I have not ate or drink anything that should cause this effect.I went 1 month between the first flush and this one.Also I had some trouble pasing one stone that was about the size of a walnut.It did not hurt but I could feel it lodge in the colen area briefly,it was just some pressure for a few minutes.I did the Hulda Clark LF.If anyone has noticed red water like this,could you let me know,please.Thanks
