If you're talking about the reddish thing in the upper right corner that looks like a fluke. The whitish thing in the poop could be mucous or roundworm. No idea about the blob stuck to the side of the toilet on the left side.
Honestly, it's vulgar to make us look at your poop and it's not helping us to help you. Roll up your sleeves, doff some rubber gloves, find something to retrieve it from the toilet, wash in alcohol, lay next to another item for size comparison and take a decent photo. You will get better responses and possibly a positive ID. Simply put, your photo is shitty.
