“If it’s just you and me, that’s okay.”

Those were the moving words of McFly’s Harry Judd to his wife Izzy when fertility problems meant it looked like their dream of starting a family may never come true.

In her new book Dare to Dream: My Struggle to Become a Mum – A Story of Heartache and Hope, Mrs Judd reveals how pair had started trying for baby shortly after getting married in December 2012.

But her rock throughout it all was her husband, who she described as “my rational mind”.

The 33-year-old former Escala violinist added: “Harry was so calm. He was able to always bring me back.

“He was just so patient. We’ve been together for such a long time. He’s been amazing and I really needed that.”

Part of the reason for her husband’s calm, she believes, was their age difference – Mr Judd is two years younger than his wife.

“He was at a time when many of his friends weren’t even married,” she explained.

“Whereas my friends were married and having children. I felt more in panic for it to happen.”

Mrs Judd said she was so focused on her fertility problems that she felt “it was almost as if I was neglecting my relationship”.

She even confessed to feeling: “What if I can’t get pregnant? Will he stay with me? A lot of people can relate to that feeling.”

However at one point during the difficulties, Mr Judd – who wrote a chapter in the book – took his wife by the hand and said: “If it’s just you and me, that’s okay.”

She added: “It was that moment for me that made me think he really does want to be with me.”

Asked if she felt their battle to have children had made their relationship stronger, she said: “Yes, definitely.”

Dare to Dream: My Struggle to Become a Mum – A Story of Heartache and Hope is published by Bantam Press. It is available from bookshops, online or as an e-book.

What is IVF?

In vitro fertilisation, or IVF, is used to help people with fertility problems have children.

The treatment works by removing an egg from the woman’s ovaries and fertilising it with sperm in a laboratory, either their partner’s sperm or sperm from donors.

The fertilised egg, called an embryo, is then returned to the womb to grow and develop.

IVF can be available on the NHS but the decision about who has it is made by clinical commissioning groups (CCGs).

Those not eligible for IVF on the NHS can have treatment at a private clinic, although one cycle of treatment can cost £5,000 or more.

Success rates vary depending on the age of the woman but can be around 30pc for women aged in their 30s, although they are much lower for women in their 40s.
