A couple months ago I saw something weird in my stool so I went to my dr and she prescribed me ivemetcin because she thought I could have pin worms. She sent my stool out for analysis and it came out negative. Today I was soaking in a bath with Epsom salts and I noticed this in my water when I got out. Could this be an earthworm that got into my water (I have well water) or is this some type of parasite. I am freaking out none the less. I'm only 20 years old. Can someone please help me
