Weird discharge (TMI)

Hi ladies, I was in the bathroom a few minutes ago and had some discharge that I've never seen before (or never noticed). First off, it was yellow. It wasn't a lot and it wasn't chunky either! It looked like a thread almost and it was stretchy. Sorry, didn't have my phone with me so I couldn't snap a pic. Any thoughts? Do I have something I should go get checked out? Thanks girls!!!
