The This Is Us actress is currently expecting her first child, a son, with husband Taylor Goldsmith, and she tells Romper in a candid new cover story that she consulted a fertility doctor before becoming pregnant, initially believing surgery would be necessary before she could carry a child. The Silver Landings singer says doctors "suspected" endometriosis. "I was fully prepared to go have surgery and fix my uterus and hopefully get rid of the endometriosis, if it was there," Moore, 36, recalls. "It was nice to have a plan and to know 'Okay, well this is why I haven't been pregnant yet.' " But as Moore geared up for surgery, a fertility specialist casually told her at an appointment that she was ovulating but noted there was a slim chance of conceiving given the issues with her uterus.

"But I was like, man, I wish I had known before. It would have been a game changer had I had that information." Moore tells Romper she kept her expectations low, even when she learned of her pregnancy. "Because of this issue with my uterus, I was very hesitant to believe it and put any stock in it," she says. "I sort of was holding my breath until 12 weeks."

"I think he's been suited to be a father for pretty much his whole life. He's been gearing up for this," the mom-to-be shares. "Like in the morning, it's funny, I'll reach for my phone and he'll reach right for whatever baby book he's reading." Adding of Goldsmith, who would normally be out on the road if not for the pandemic, Moore says, "We wouldn't have spent this gestation period together — he would have been touring. And it would have been fine, but having this experience together makes me feel even more solid and even more excited to be a parent with him." Moore adds that she wants to "raise an intelligent, feminist, loving, compassionate young man, who respects women, and who understands boundaries."

The pair announced their pregnancy news in September, revealing that their baby boy is due "early 2021." Since becoming pregnant, Moore says to Romper that singing, for her, has changed, and she often sings a tune for her baby. "Singing feels so different right now, with this dude in my belly," she says. "I don't find myself feeling stressed out about how my voice sounds, or am I hitting the right notes? It feels good to just open my mouth and sing right now, which is weird, but I like it."
