early heavy period? :/

So yesterday my period started. It was early by a week. When it started it was so light that it didn't even cover a section of the panty liner I wore for the whole day. I only really seen it when I wiped, and it was pinkish red like spotting. Just in case, I wore a pad to bed. I'm so happy I did. I ended up leaking through (yay). So today, I've went through 3 pads, 3 pairs of underwear (it's so heavy I keep leaking), and two pairs of pants. It's now even heavier, like a dark red and some little clots. Has anyone experienced this? Can anyone give me some insite on what's going on with this incredibly weird period? 
Help please.
