Help with strange objects after BM

I have been treating for roundworm using the cxvrm2 from systemic formulas for about 2 months. Every now and then I pass these objects which always come out alone (without other feces) normally after a large bowel movement. I have been suffering symptoms for 2+ years and am about at my wits end with this ailment. These objects are NOT mucus as they are nearly impossible to break up using a butter knife that I keep nearby for inspection. I can update later today with a full story of my affliction but am currently at work so have to keep it kind of short. Any help identifying what this might be would be great thanks.
