Thanks for your reply! No, I wasn't taking anything that would chase worms out of the small intestine. Just eating a regular diet and no recent cleansings or anything.
I thought that roundworms were, well, round; you know, like a piece of cooked spaghetti. These things of mine were flat. However, is it possible that as they make the long trip thru the intestines they get "deflated" and therefore look flat?
Correct me if I am wrong here - it seems that the official medical photos of parasites are intact, ie, they must've been removed from a dead body or during surgery. It's anyone's guess what we are dealing with after they are all damaged and twisted out of shape by the time they exit the rectum.
