Officially Hate BCP

Not more than 9 days after my BCP scheduled period, I started yet another one, but this time it came back with a vengeance.
Last night I woke up around 2am to severe cramping in my lower abdomen. I've heard of miscarriages described, and I am guessing I just had an insight as to how they feel. No, I didn't have a miscarriage; just cramps, I guess. It felt like a contraction, and I remember wanting to push because I thought it would make me feel better but any pressure only made it worse. I was doubled over screaming, and eventually vomiting as well. Hubby got me settled into bed, and put a heat pad on my tummy. Eventually I felt well enough to fall asleep.

Why is this happening?
A) I thought BCP was supposed to control bad cramping.
B) What in the world is with the twice a month, heavy random periods?!
C) Wouldn't even know if they're preventing pregnancy because I am not having sex! You can't have sex when you're constantly on a period and your sex drive is in the gutter! (Well, you can have sex on your period but it's not something I practice. Ew.)


ARGH!
