She says: “When they told me I had no womb I was so confused I felt sick. My biggest fear was never having children.
"Suddenly a huge piece of my life was missing. I felt like half a woman and was embarrassed. How I was going to tell a guy I was genetically male when I started dating?”
A ray of hope came in 2007 when a new specialist at Royal Derby Hospital found a tiny womb missed on previous scans.
“It was only a few millimetres, but it was a start,” says Hayley. “He was optimistic it would grow. I still couldn’t conceive naturally but I could have the option of IVF.”
The first step was a course of hormone tablets to give her the right levels of progesterone and oestrogen. They would stop her suffering osteoporosis and create an environment where her womb could grow.
