2.00am, Saturday morning: You wake up in the dark. The bed is warm and your husband sleeps soundly next to you. There’s a rhythmic cramp spreading throughout your pelvic area, like a period cramp. But it feels too repetitive for that. You don’t know much about your pelvis except that there’s been a lot going on in that area of late. A person’s head. Their fingernails, nose, feet and elbows. All in there. In that comfy cocoon you built, a baby-sized sleeping bag for your passenger. Your friends tell you you’re a wizard.
