Speaking to Now magazine, Katie said that she began to experience stomach pains whilst on in Cape Verde in April, before she even knew she was pregnant. And just days after discovering she was expecting - Katie reveals the terrifying moment she thought she might her child.
The star, 35, describes how she was shopping in Tesco 'still totally shocked about being pregnant…[and] I suddenly felt these awful pains. I went into complete panic.'
Seeking her Doctor's advice, Katie discovered that there were complications with the pregnancy - and credits 27-year-old husband Kieran Hayler with keeping her calm during the stressful time.
'All I thought was: "Thank God Kieran's with me." He was brilliant.'
But Price has admitted she also feels sorry for her tomboy lover, as he's only ever known her when she's pregnant, or just given birth.
'After this one I want to take five years off to get my poor body back into shape because he's never known me on top body form…The man needs to know what he's got,' she said.
Katie gave birth to son Jett eight weeks early in August 2013, and with her fifth child expected in summer 2014, both kids will be in the same school year.
Mum-of-four Katie also revealed she's 'never been this happy with anyone before,' adding that she hasn't been as hormonal with this pregnancy because Kieran has made her so happy.
