The yellowish looking ones look like flukes. Small flukes. The red ones may be parts of a worm or small worms. I had something similar.
Here are a couple of photos of a large worm and a small worm along with a full size fluke.





I did an extensive protocol for months to get rid of these worms and flukes and a few unidentified things. I could never identify them. I am apparently a freak of nature and expel the critters without digesting them. Parasitologists identify parasites from their eggs as full sized examples are very rare. I believe partly because few people go digging around in their stools. You get used to it.

You can find my protocol in the VERY FIRST entry on my blog, Getting the parasites Out. Go to Blog, new blogs, scroll to #4190. Open it up and then navigate to page one. Scroll down to the very first posting.

Getting rid of parasites is a do it yourself project. Unless you can find a knowledgeable Naturopath, most doctors are a waste of time and money.
Good luck. Happy to answer questions.
