Parasite or gallstone?

So these came out yesterday in a routine coffee enema. Never seen them before, but there was a lot of rumbling in my lower intestine. I wasn't sure if they were some sort of stone or if they were alive at some point. They don't compress much if I squeeze them but they shred a bit if I apply pressure in different direction. There was a lot too, not just these three. Some were a bit stringier and some were more round. I think some may have had blood vessels or tracts of some sort but it was hard to tell.
