liver flush people, fourth flush mixed results

Just finished my fourth flush. My last flush was unsuccessful with maybe one or two stones, no chaff. This one gave me lots of chaff, maybe three toilet bowls full, some sludge (two toilet bowls) and about 10-15 pea sized stones that crumbled when I tried to pick them up with chopsticks.
They looked like they were newly formed clumps of chaff. Does anyone know what could be going on? Did my body produce all of that since my last flush which produced no stones or was it just "hiding out"?
