Passed this fluid-filled sac in my stool. Very rubbery and gelatinous. I have had 2 years of pretty bad health and worsening digestive issues. I do not eat gluten or dairy. I have been diagnosed with Blastocystis, but those are microscopic so I am not sure what this could be. Could this be a tapeworm cyst? I have had lower right abdominal pain lately.

Size: smaller than a pea.

Does anyone know what this might be?
