Are these gallstones? Help!

I need some help here! I am on my 2nd Master-Cleanse and pass a stone just about every day. In fact, have passed them since the first day! I have researched and researched just dying to know what these are made of, and what/where they come from, but NONE of the pictures I have found even remotely resemble what is coming out of me! ...sorry, kind of graphic.

I understand that stones can be different colors and sizes, but I would really like to know if anyone has any "stone" knowledge, or if any of you fasters are passing them like I am. I read somewhere that Gallstones are not actual "stones" because they float, rather than sink to the bottom of the bowl, and instead of being hard, they are rubbery and somewhat soft. This describes my stones, but mine are white/cream colored, and all perfectly oval in shape. All the exact same smooth shape and size. NOTHING I have seen in my investigation has looked like these!!!

I am sorry this is somewhat grose, but if anyone can handle this type of thing, you guys can. Too bad I dont have a pathologist handy! I was just a bit concerned and VERY curious. When foreign objects that you didnt know existed, much less knew were inside of you begin coming out, it definitely peaks your interest!

Any wisdom from any of you would be greatly appreciated....
