Way more discharge than usual?

Elizabeth • Tracking my irregular period day by day! :p
I've been on Mirena now for a year, and I love it! I was just wondering if anyone else has experienced more discharge than usual? Sometimes it feels like I've sneezed or coughed on my period, like a waterfall of stuff. It's definitely not urine, but it's so unexpected that I feel like I should wear a pantyliner at all times so it does not create a wet spot on my jeans. ):
