Byrne, who also hosts the Making Babies fertility podcast, said writing her book was “emotional” and “in a way cathartic”.
“I know it’s a bit of a cliched word but it does provide a little bit of closure too, I guess,” she said.
The book includes chapters reflecting the fertility experiences of a number of other celebrities who have appeared on Byrne’s podcast, including presenter Gabby Logan and comedian Geoff Norcott.
“I look at Jemima every single day and I’m just so grateful,” said Byrne.
“I’m glad that I am able, hopefully, to use my platform to hopefully have a positive effect and maybe help other people feel less isolated.”
Asked if she had any advice for others experiencing infertility, Byrne said she wished she had been kinder to herself.
“I think it’s very easy when you get some bad news about a cycle, or you’re having a bad time dealing with it, that you catastrophise and think 10 steps ahead,” she said.
“And before you know it you’ve written off any chance of anything, which is very easy to do because it feels so hopeless.
“Nobody knows what’s going to happen 10 steps down the road, so just try and deal with what’s happening in that moment. I wish I’d done that more.
“And also been a bit kinder to ourselves, and yourself in the process. Take that time to find little bits of joy where you can and take time out if you need to from it.
“Because it can be all consuming, friendships-wise, family-wise, it affects everything. So you really need to be kind to yourself.”
