Please help me ID if these are parasites or not

This was just tonight after noise and cramping in my abdomen:

This was last week after the same conditions:

Back in November this came out after cramping:


I get bloating and early satiety, constipation, cramping, loss of appetite, frequent trips to bathroom only to pass just water and these things. My GI just thinks I have IBS and mucus, but they don't look like mucus. Please help me.

I am a 19 year old male. Active. Athletic body type. Otherwise normal lifestyle, live in suburban USA. I have health anxiety so I am very particular about my health and this is freaking me out.

This has been going on for 5 months.
