Help!!! IB?!

So I ended my period 9/19 weirdly enough I started bleeding lightly for a couple days on 10/2 (periods are always super regular) and my actual period wasn't supposed to start until today 10/13. Just went to the bathroom and wiped and have this.. could this be IB!? I hate that I am posting a pic of my cm but I've never had this before or a weird cycle like this 🤔🤔
