While the 42-year-old was busy working in L.A., on tour with his brother, Val Chmerkovskiy, in New York and away in Ukraine judgingDancing with the Stars, the Peta Jane Beauty founder had to figure out ways to redirect her son’s questions all on her own.

“I guess that’s been another really hard part of it because he sees other kids with siblings,” Murgatroyd shares. “And of course when [the pregnancy] goes, I kind of just stop saying it and he stops asking. I never told him I lost them or how. I just stopped saying it. And then for a while he stopped asking about it.”

“There was one comment in particular: How could you not [have another child]?” Murgatroyd recalls. “The ‘how could you not’ threw me off the ledge. It was like, if only you knew what was actually going on with my family, you would never say that.”

As Shai’s gotten older, he’s started to ask more questions.

“I think when he looks at other kids and sees them with their siblings, that’s hard,” Murgatroyd says. “And that’s hard on me when I see him feeling a type of way.”

Doctors eventually diagnosed Murgatroyd with polycystic ovarian syndrome, a hormonal imbalance that can cause a woman not to ovulate regularly. The diagnosis has calmed the nerves of the reality star, who has started in vitro fertilization treatments.

For the first time in a while, Murgatroyd is feeling positive to have good news to share with Shai.

“I could be pregnant in like a month-and-a-half, I think,” Murgatroyd says. “So [it] might be the happiest day. I honestly feel like I’m in such a better place just because I don’t feel like I have anxiety right now. I feel like I have answers. I don’t have any other words but hope and positivity and just crossing my fingers that this is going to work.”
