Despite the multitude of problems my lady problems have, I've always been pretty regular and my cycles are long (35-37 days).
I started my period today on day 26. What is this nonsense? Why why why? I was supposed to do some stuff tomorrow and my uterus just ruined EVERYTHING.
What can cause your period to be suddenly early? I really can't remember being more stressed out than usual or doing anything differently this month. I'm 22, so I'm not menopausal or anything. Also I really doubt I'm pregnant unless some bizarre freak accident happened.
