Erin Langmaid welcomed baby Isla in her bathroom on Oct. 29, though she had no idea she was pregnant

Model, 23, Didn't Know She Was Pregnant Until She Gave Birth to a Full-Term Baby in Her Bathroom

An Australian model recently had a life-changing surprise when she gave birth to a baby in her bathroom, despite not knowing that she had been carrying her daughter for nine months.

Erin Langmaid welcomed a healthy 7 lbs. and 7 oz. baby girl, Isla May, on Oct. 29, but says she had no idea she was expecting after not showing any typical pregnancy symptoms and consistently using contraceptive injections, 7 News reports.

“I wasn’t showing obviously because I fit into everything,” Langmaid, 23, told the outlet. “It’s just really bizarre.”

Langmaid and her boyfriend Daniel Carty’s world was flipped upside-down two weeks ago when the model started feeling ill and took a trip to the bathroom.

Within just ten minutes, Langmaid said her daughter had unexpectedly arrived in a “dramatic” fashion — a moment that Carty, 31, said also caught him off-guard.

“I heard a scream and I ran in there and then I saw the little one and I thought, ‘Hang on, there’s two,'” he recalled to 7 News of his shock, which quickly turned to panic when he realized Isla had stopped breathing after making her grand arrival.

Thinking on his feet, Carty called 000 (Australia’s version of 911) and had the operator walk him through the steps to restore his daughter’s breathing and save her life.

Thankfully, Carty was successful in his attempts and his girlfriend and daughter were soon rushed to the hospital, where doctors determined that Langmaid had experienced a cryptic pregnancy.

A cryptic pregnancy, also known as a stealth pregnancy, is when conventional testing methods fail to detect a mother is carrying a child, according to Healthline.

One in every 475 women experience a cryptic pregnancy which goes undiscovered until the mother is 20 weeks along, News Medical reports. Some others, like Langmaid, don’t learn they’re pregnant until the baby arrives.

Weeks after the major surprise, Langmaid and Carty are now settling into their new lives and unexpected roles as parents.

Carty shared the exciting news on Instagram with his followers on Nov. 1, alongside a sweet family photo of him holding his new daughter while Langmaid watched on.

“We want to share with you our new little family member. Isla May was brought into the world on Tuesday night, she lived in mummy’s tummy for 9 months without letting us know,” he wrote. “After an extremely tough few days both mother and daughter are perfectly well and ready to go home.”

“The support of our family and friends is something that we will never be able to thank them enough for,” he continued. “To Erin the courage you have shown is something I didn’t think possible, you are an incredible person and will be an amazing mum.”

“Now after a big week we look forward to life as a little fam with the most gorgeous new little addition and all the great things that come with that! Thanks for all the support it’s been amazing xx love the Carty fam” he added.

Langmaid also shared the big news on her Instagram, calling the surprise birth “the hardest week of our lives” and noting in a separate photo of Isla how she and Carty “were blessed with this little legend.”
