@shesnotcrazyseries: Awesome Facts About Pregnancy I was in the room for two of these and knew almost none of it. The placenta isn’t her organ. It’s built from the baby’s cells. A foreign organ plumbed into her bloodstream, running the pregnancy from the inside. Which is why her immune system has to stand down for nine months. We can’t put a kidney in a bloke without a lifetime of drugs. And the ceiling for human endurance, measured on people running across continents, is about two and a half times resting metabolism. Pregnancy runs at two point two. Nine months at nearly ninety percent of the human maximum. Calcium out of her bones. Iron out of her blood. And if there isn’t enough, the baby gets it first. She didn’t just have a child. She was rebuilt by one. #shesnotcrazy #marriage #relationships #understandingwomen #cycleawareness
