Dr Simon Atkins presents a science-based series which follows 100 couples on the journey from conception to childbirth. The pressures of pregnancy are taking their toll on some couples. Despite being just weeks away from the birth of their first child, Kate and Peter have decided to part, while Jane is suffering ante-natal depression. As 62 couples prepare to give birth, we also catch up with the ones who have not conceived and hear their plans for the future.
