This is the heart-warming moment a dad was left speechless after his wife announced she was pregnant following a lengthy IVF battle.

Beth and Jamie Wilson from Wiltshire were just days away from starting another expensive round of private fertility treatment.

But Beth felt nauseous, and two tests confirmed the 34-year-old was four weeks pregnant.

She wrapped one in a gift box with a note "to Daddy" and pretended to be taking a selfie while filming her husband opening the package.

He thought it it was a homemade present from their first child Eli - who they spent seven years conceiving with IVF. The video shows the carpenter casually opening it up before his mouth falls open when he sees the test.The father-to-be shouts: "What's this? What does this mean? What? I'm confused." But realisation dawns and he bursts into a smile before shouting "are you kidding me?!" at his giggling wife, and starts to tear up.

The video ends with the delighted father joking with his wife, telling her "don't post this!"...something she duly ignored.

The natural conception has saved them £2000 in fertility treatments - the couple don't qualify for NHS-funded IVF as they already have one child.

The couple are having a baby boy which is due on June 16.
