Good Lord (beware, possible TMI ahead)

I started my period when I was 8 years old and they were very sporadic. The bigger I got, the more sporadic they were. In the last few years, I might have one period a year. I seriously got used to that and it was SO NICE (though probably not nice for my body). Now, after surgery, my periods are trying to come regularly. So far, hadn't been a bad thing. But this month I have THE MOST HORRIBLE cramps. I never understood what women were talking about and why they had to take midol and all that jazz, and I am paying for it now! Yeah, I just wanted to... whine and stuff.
