I am a 32yr old woman and have no other symptoms or diseases except for 3 bladder infections in the last 9 months, one very bad but all gone with antibiotics, lots of yoga, and have a very healthy (mostly vegetarian) diet, especially in the last 6 months.

For several weeks, every several days as I was digesting a big meal, I'd temporarily feel sort of a gas-like or digestion-type flutter in the lower left of my abdomen, and I had a feeling I had something stuck in there. No pain or anything. Yesterday morning I noticed a little string or something (I thought it was an old sausage casing!), stool-colored, and had to pull it gently to free it. I looked at it and it really looked like stool. Not worm-like. I still feel fine, other than being really grossed out. I haven't noticed the flutter in the lower left abdomen and my stool is, as always, twice a day and a "3" on the stool firmness scale.

Could this be old gum? Just a weird thing?
