Watery blood?

I had a 27 day cycle this month. Got my period on April 12. Right off the bat I wasn’t having the crazy cramps that I usually get and I’m still not experiencing them. Yesterday (it’s 3am right now) the 13th, I was laying down and I could literally feel me period blood pouring out of me like a waterfall basically. The blood is just sitting right on top of the pad, it’s super watery. This hasn’t happened before. I did take a picture but I don’t really want to show it as I find it gross. The blood is a very dark shade of red. What should I make out of this?
