Zoe has been speaking up about miscarriage since the finale of Married at First Sight.
And back in the real world, real things happen.
To the couple's delight, Zoe fell pregnant, but she suffered a miscarriage during the first trimester.
They were both devastated and struggled to cope with the loss. Now, Zoe wants the subject of miscarriage to be something that's spoken about openly, and not a taboo subject for couples to endure alone.

Zoe and Alex told the whole country about Zoe's miscarriage on A Current Affair on her and Alex's first wedding anniversary.
