And from someone with medical training: Don't worry to much. However check ur stool and if it turns red and you haven't ate a shit ton of hot sauce that is where you go to the doc because you could have lacerated (cut) your intestine (large or small). this would require surgery if it was healed and you would need some antibiotics. You should know in a day - 3 days if that happens.
Sparknotes: If you poo blood go to ER DOC... if not don't eat plastic again
Don't take life to serious, you will never get out alive.
