"I do want to, but I’ve got to mentally check that it’s a good idea to do. And also physically because I am 45 as I always say, nearly 46. So it’s a little bit dodgy."
She continued: "Jamie is still up for it, kind of… not really. I haven’t got long, maybe another year and then I really will just shut that chapter off because I am very happy and I am pretty full up at the moment as it is. But just that little baby, it’s a terrible thing to keep wanting something and you can’t help it."
Discussing the trauma of the miscarriages, Jools said: "I went to see the doctor the other day and he said, 'How are you mentally?' and I thought about it and I went: 'Well, this is the fifth one now', I had two before River, and they’ve been early ones, the last two have been at six and a half weeks.
"So I just feel… I’m really good at going 'Right, I’m pregnant but it won’t work so I’m just going to carry on,' whilst everyone gets really into it and I have really learnt to not because I’m kind of not very positive about it."
Jools and Jamie recently celebrated their 20th wedding anniversary, and in a touching social media tribute to her husband, Jools shared the news that the couple have suffered five miscarriages up through the years.
"We have created 5 wonderful children and lost our 5 little stars in the sky," she said.
Last year, Jools reflected on her losses during Baby Loss Awareness Week, writing on social media:
"A beautiful wave of light to mark the end of an always emotional Baby Loss Awareness Week. Thinking of all the families who have lost a cherished beautiful baby, either through miscarriage, stillbirth or neonatal death.
"It is an absolute privilege to have come across some wonderful, strong brave women and families through Instagram who proudly tell their story of their own baby loss and through that support thousands of people going through the same thing."
