I've seen pics of pinworms and other parasitic worms in feces and they all look basically like worms.  But for the past several years (I forget when this started) I've seen string-like things in my poop, but they're not white or thick like worms are. They're super thin and the same color as the poop.  I don't have any other symptoms other than occasional gas and bloating which comes and goes.

I know that worms are really common and not a huge deal but I'm really afraid of hookworms- this doesn't look like the hookworms I've seen online but you never know.  I'm probably going to see a doc about it soon.

This "worm" seems to be splitting in 2 different string and holding onto some fragment found in my feces (corn?) so I'm not sure, once again maybe it's just a fiber.
