What is this?

So, I felt like I was having a little bit of discharge about 20 minutes ago so I wiped and this is what I saw. My period is due in two weeks, as you can see from my birth control pack and my eve calender. I'm feeling some very slight cramps now too. All day, I've had a tiny bit of clear discharge occasionally but I've never had anything like this before my period. The discharge I usually get before my period is light brown, not light pink, and usually starts happening a week to a week and a half before my period starts. What could this be?
