Anyone else feel "weird" & have clay colored stool?

Hi! I just did my first cleanse this week. I've had two attacks and don't want any more! They hurt!!! I didn't count but estimate 50 small stones the size of grapenuts, peas and seeds. I also got two stones the size of peanuts. All day I have had a feeling of pressure in my upper abdomen. My right side under my rib cage and around to my back feel like it has a band around it. Feels like I need to burp to relieve the pressure but burping doesn't help. It's not painful, just uncomfortable and feels like it might start to hurt (if that makes any sense). Also, lots of indigestion which I never have. I'm worried I'm going to have another attack. I am also concered because I read on one of the sites that a clay colored stool indicates a stuck stone. I've had two clay colored stools. If I had a stuck stone wouldn't I be in a lot of pain? Do I need to do another flush? When? Tweet
