"I used to be free of all such woes. My period was always light and infrequent, and I was joyous in this. And then whatever evil demon beast creature who arranges these things, one day, took notice of my blessed, innocent uterus. And it said to itself, "That can't be right! You need to suffer more!" and one month it was just like BAM and my uterus said "AIGH" and I said "JESUS FUCK WHAT THE HELL."
And now I'm on birth control!"
