Is going on with my cycles?? I got

on 4/17, it lasted 4 days, normal flow. Then I got it on 4/30, and it was "normal" but only lasted that day. Then I got it again on 5/11, and it only lasted 2 days. Now here are my symptoms:
MAJOR hot flashes...to the point of sweat dripping off my face, I was bloated, but that went away. I'm very thirsty, and I was tired a lot, like I was gearing up for her, but all that went away too. I'm eating like a cow....any ideas?
