House: Pregnancy causes all kinds of chemical and biological changes in a woman's body. Or a girl's body, as the case may be. In extremely rare cases, everything goes haywire. It's called TTP. Blood starts clotting like crazy, clogs the vessels in your brain and kidneys. Red blood cells end up getting shredded as they squeeze past the clot like a fat guy in a crowded bar. I'm sure you know what that's like. You're only 12, but you're all grown up, right? Travel on your own, hang out in hotel rooms getting room service with your teammates, maybe someone sneaks in a couple of beers, you start playing spin the bottle…next thing you know you're waking up in nothing but your socks.
