Heidi was 9 weeks pregnant when she found out she was expecting

My Extraordinary Pregnancy explores what it's like to be pregnant in extreme situations. 

Last season's astonishing women included a blind mum-to-me, a body-builder, and a woman allergic to her own babies, but this time, our mothers’ stories will be more intimate and extraordinary than ever before.

Season 2 follows more remarkable parents-to-be through their extreme and unusual pregnancies, giving the unique perspective of both the mums-to-be and the medical experts looking after them.
