Recently I passed what looked like an egg in my stool and I had never seen anything like it in my life. 3-4 weeks later I passed another one and it was the exact same size, shape and color. It looked like one of those big jelly beans. I went to quick clinic doctor and he didn't find any parasites, then I went to a gastro doctor and he looked clueless. I'm trying to find out if anyone has seen anything quite like it. You can see a picture of it at this address.
