BBC News presenter Kate Silverton has said that becoming pregnant again is "beyond a miracle".

Silverton had experienced fertility problems for years and underwent IVF but has now conceived naturally for a second time, with her second child with husband Mike Heron due in two months.

She told Hello!: "To be blessed with baby number two seems beyond a miracle. It seems it's also beyond the doctors' understanding, too. It's simply amazing and we are so excited.

"I have felt such utter joy in motherhood that I just wanted the chance to do it all over again. Despite my limited chances, I thought it was worth trying again. I just wanted to have one more try naturally and see what happened."

She added: "I think it helps for women and their partners to be able to talk openly about what they are going through and to know they're not alone, and that even with the tough times there can always be hope.

"Mike and I struggled to have children for the last seven years. Now it feels as if we're coming to the fruition of a long but lovely journey. I would love to know that there are others out there who are able to do the same."

The couple's first child, daughter Clemency, was born in 2011.
