Ok I have the same thing. I looked at them up close under my magnifier..well one I examined and it looked tubular, so I thought it was a kidney stone. I saw another one today, and when I examined it, it looks like a broken egg shell. How spooky. I was doing the Kreuger Wormwood Kit cleanse when I first saw them but I stopped midway through the cleanse cause I didn't feel it was doing anything.
