Sounds like a fluke to me. There are redish round worms also, but my worms all come out without a skin on them.
Flukes are usually shaped like a pod coming to a point at both ends and can be curled up to look like a ball when first expelled.
Usually you will see flukes at first, they are some of the easiest parasites to be killed. I have had off white and red flukes.
Good for you, they can cause cancer in your future, keep cleansing...heyjude
