Period from hell!!!

Ugh! I always have very abnormal and unpredictable periods!! This month's was late, I just started yesterday {6 days late} and I feel horrible!! I have had a migraine for a few days, I want to eat anything and everything but I feel super huge, in ALOT of pain and all I want to do is sleep! Does anyone else struggle with these same issues when Flow comes to hang out for the week?!
