Twice in the last few months i have farted and pooped my pants at the same time. I have had no warning. I did not feel like I had to poop, didn't feel constipated nor have diarrhea, my stomach didn't hurt at all, wasn't bloated, didn't even really feel gassy. It seemed like a harmless silent fart but came with a load of liquid. I am so embarrassed. Both times i have been home alone thankfully. However, im terrified it will happen again when i am in public or with my SO or while i am sleeping. What could be causing this all of a sudden?
