Something strange coming out of platy

[Briggan]

Hi! I just noticed a white oval-orb thing hanging out of my platy. It seems to float upwards so that’s why it looks like it’s on her side. She also happened to be pooping at the same time so it might be just that. Any idea what this is?

It detached and is at the top of the tank...
