"Pregnancy: it's the thing that made us, yet it's also a topic that's plagued by taboos, frequently politicized, and for roughly half the population, shrouded in unknowable mystery. It's also, despite the pastel-hued Instagram posts that will try to convince you otherwise, bloody and gross and alien and primal.
All of this makes pregnancy a theme that naturally fits well with horror movies. What happens when a parent doesn't feel a connection to their child, or can't keep their kid safe? What if outside forces take control of a woman's body? The often-unspoken anxieties that go hand-in-hand with human reproduction have been channeled through the safely metaphorical conduit of horror for decades, resulting in films that expose tough truths and reveal deep-seated fears."
