In a BM today, I noticed a very large round and tan ball approx. 1" in diameter embedded in the stool... It didn't float and it was quite a firm thing... Not green inside either (Tanish)... Unusual I'd say or I never notice such a thing (It was obvious)!!! Is it something positive???
Since you recently completed a liver flush, it could be anything. I remember reading one post and they continued passing "things" for eight months after their flush!!
