Molly Sims is partnering with Us Weekly to talk about fertility and share her journey to becoming a mother of two — and soon three! The 43-year-old actress, married to producer Scott Stuber, 47, spoke candidly in a video for her YouTube channel about freezing embryos, trying IVF twice and ultimately conceiving naturally with each of her pregnancies.

“I decided to freeze my eggs before I met Scott,” Sims shares in the video for the Molly Sims YouTube channel, a lifestyle destination that she created with Awestruck network. “I went to see Dr. Shahin Ghadir at the Southern California Reproductive Center. The maternal clock all of a sudden just started happening.”

But the New York Times bestselling author ended up waiting until after she met her husband to go through with the freezing process: “We ended up freezing [embryos] about nine months before we got married in September of 2011.”

Sims didn’t need to use her frozen embryos and got pregnant naturally with her first child, Brooks, 4, in 2011. “Honestly I got pregnant on my honeymoon!” she shares in the video. “I think because we had froze, and because I had in the back of my mind a safety blanket — a safety net — I got pregnant.”

When Sims and Stuber were ready to give Brooks a sibling, the conception process took a bit longer. “We tried IVF twice with Scarlett [who is now 19 months],” Sims shares. “I was just about to do another round, and there you go, there was Scar!”

Due to have her third baby in December, Sims says this current pregnancy was a surprise. “After five tests we were like, ‘OK, maybe this is happening,’ But it was definitely shocking.”

Sims is happy to share her fertility journey with others. “I think what women put themselves through — the emotions and the shots and the hormones and the weight gain and then trying to lose the weight — it’s just a struggle, it’s so difficult.”

The actress has advice for others dealing with fertility issues: “Try to have at least one person you can talk to and really be open with.” Sims continues, “There are a lot of dark moments … it’s sure not easy, and I got very, very lucky to find my prince and to have my family.”
