I've been getting them too- first on anti- parasite herbs/ parasite cleanse. After a month on it & still getting stuff (worms, flukes, biofilms, etc.) I moved onto the Dr. Jennifer DanielsTurpentine protocol / "candida cleaner" (which is geared towards candida). When I took it with castor oil yesterday (vs sugar) I passed Tons of those things with a huge load of liver flukes & bile. I don't know what they are- I guessed they were somehow related to flukes, though I could be wrong. It could be candida. I found one source online that said they were Ascaris egg sacks (& I def had ascaris). So, I have no idea. I've preserved a bunch of these in a jar with alcohol as well as some of the flukes- I don't know if there's any point in taking them into the doctor or not.
Anyhow, best of luck!
