Blood In Stool, White Substance Floating, Not Pinworms

Today i went to the bathroom, its been 3 days since my last bowl movement, and this isnt all that abnormal seeing as as long as i can remember ive been having bowel movements every other day, but today i couldnt poop that much, it was smaller than usual and i saw blood in my stool and white cobweb looking things floating at the top of the water afterwards. Also it didn t hurt as it usually does, i ve been drinking more water than i used to too because i was sick for a week 2 or 3 weeks ago. Also the strands were pretty long and i havent noticed anything like it on my bed so i think it unlikely to be pinworms.
