Hailey Bieber is opening up about a deeply personal chapter in her life — and the unexpected medical challenge that made her pregnancy far more complicated than fans might have realized.
The 29-year-old founder of Rhode recently appeared on the SHE MD Podcast, where she spoke candidly about welcoming her son Jack with husband Justin Bieber. During the conversation, she revealed that doctors had previously warned her about a uterine condition that could complicate pregnancy.
The topic came up when Hailey was asked whether she and Justin had been actively trying to conceive — or if the pregnancy came as a surprise.
“It was a surprise. She told me this was going to happen because she was like…” Hailey said, referring to her OB/GYN Dr. Thaïs Aliabadi.
“And I told her like, ‘Don’t get pregnant!’ ” Dr. Aliabadi interjected, before asking if Hailey wanted to share about her health diagnosis.
Hailey explained that doctors had been monitoring a condition known as a uterine septum — something she had been aware of prior to conceiving.
“Yeah. So I had a septum in my uterus, and Dr. A kept saying, ‘Well, we need to look at this and keep an eye on it before you get pregnant because it could potentially be an issue,’” Hailey said.
“‘I don’t really know. We’ve got to see. I might have to give you a small surgery for it. Not sure.’ And I was like, ‘Okay. Well, I’m not thinking about getting pregnant right now, so we’ll just cross that bridge when we get there.’ And then I magically got pregnant.”
The news came as a shock to her doctor.
“And then she calls me, and she’s like, ‘I’m pregnant!’ And I’m like, ‘No!’” Dr. Aliabadi exclaimed.
During the podcast episode, Dr. Aliabadi explained what a uterine septum is and why it can complicate pregnancy.
“So uterine septum is genetic. Again, we’re born with it. So basically, imagine you have a normal-shaped uterus. But inside the cavity of the uterus, imagine this little wall that comes in, this thin wall that comes in. You can have a mild, moderate or a severe septum. Basically we measure it on ultrasound. If it’s less than 1 cm, we call it mild. If it’s 1 to 2 cm, it’s moderate.”
“Yours was moderate,” she told Hailey.
“It affects 1 to 3% of women, and with moderate, you have a higher risk of miscarriage with the pregnancy. And so the risk for her was about maybe 25 to 40% risk of miscarriage. And a 10 to 20% risk of preterm delivery.”
Hailey admitted that the possibility of delivering early became the biggest concern as the pregnancy progressed.
“Which I think was our bigger scare. Because we realized as the baby was growing, the septum it was, you know, expanding. Everything was opening and doing what it needed to do, luckily,” Hailey added.
Despite the risks, both Hailey and her doctor remained cautiously optimistic.
“I never forget, as I was telling her, ‘Well, these are the risks.’ And she looked at me, she’s like, ‘You know what? I believe that everything’s gonna work out fine.’ Remember this? And I looked at her, and I’m like, ‘I think so too,’” Dr. Aliabadi shared.
The doctor also used the moment to highlight how often uterine septums go undetected. According to her, many women don’t discover the condition unless they experience repeated pregnancy complications, which is why she encourages patients to seek advanced imaging if concerns arise.
During her pregnancy, Hailey also underwent a PreTRM blood test designed to estimate the risk of premature delivery. The results came back low-risk.
Still, she couldn’t help but worry — especially considering her family history.
“I was convinced I was going to go into labor early because of my mom’s history… but my body had its own plan,” Hailey went on to say.
For Hailey, sharing the story now is about transparency — and helping normalize conversations around women’s reproductive health.
It’s also a reminder that even when things don’t unfold exactly as expected, sometimes the outcome still finds its way.
