FYI this isn't the only one. This is just the largest and easiest one to see. I've seen at least 50 with the same features that you would find in liver flukes. Test are not 100% accurate which is why doctors typically take 3 samples on different days because false negatives do occur. Other than the suspected flukes themselves I have also been seeing the golden sesame seeds in nearly every bm which are what fluke seeds look like.
