When I described something I had passed during my 1st flush, I was told that it was probably a liver fluke. It was very pale, like a garlic bud, and also about 4 or 5 times the size of the peas. It looked soft, and also it looked like it had little veins on the one end of it. When I did an internet search, I did find that it looked like the pictures I saw. Perhaps this is also what you had. Unfortunately, this was some time ago and I don't remember the site. Sorry.
