Liver flukes are extremely rare to get in the states. You're more likely to get struck by lighting, so unless you got them confirmed by a doctor, don't go down that road thinking you have them.
I lot of people do herbal cleanses, which makes you poop out undigested food, and they think the undigested food looks like a variety of parasites and they think that's what's causing all their problems. I have yet seen one person at CZ who said they saw parasites in their toilet actually get them confirmed by a legit doctor or lab test. Not one.
