The actress joined Holly Willoughby and Phillip Schofield on the sofa today (March 13), and spoke about her new pregnancy with husband Matt Kay, as well as the nerves they had beforehand given what had previously happened.
"We've been together half our lives. You think, 'I'll get married at 20-something, then I'll have a baby, two years later I'll have another baby,'" Lacey recalled of their first attempt. "Then you get there and think it doesn't work like that for everybody.
"We couldn't believe it – we got a positive pregnancy test. You think of names, then we got to seven weeks and we sadly lost it. It was heartbreaking, my whole world crumbled. I couldn't understand it. I didn't know anybody who had been through anything like this.
"It's a really confusing time, I thought, 'What did I do?' You sort of think, 'Was my steak not cooked properly? Did I lift the box?' You drive yourself insane about all these things you might have done."
Lacey revealed that they lost a baby on their second attempt too, again at seven weeks, though admitted that they were "frustrated" when they were told by doctors on paper that it was "normal".
The pair are now expecting a child together, though Lacey said that the two miscarriages have taken their toll, recalling her initial hesitation when she discovered she was pregnant: "Don't get excited, and I sort of ignored it until I was about 10 weeks.
"It was not until I got until 20 weeks that I thought [we're going to have a baby]."
Lacey admitted that she noticed similar symptoms at seven weeks again during this pregnancy, though to her relief was told by the doctor that the baby had a heartbeat and was helped after being given progesterone pessaries – which is used for IVF.
"It does help to talk about it," Lacey added after Holly suggested it was important to be open so that women going through it could get support from those around them.
