Help!

Erica

So I started a couple of days early, or really on time, 28 days. My cycle fluctuates 2-3 times a year from 34 to 28 days. Anyway, I soaked through 2 jumbo overnight pads in less than 3 hours! Also, TMI warning, a huge clot expelled, like the size of a plum! It was gross!!!! Am I having a miscarriage?! This is crazy!
