Erin Langmaid is a 23-year-old model from Melbourne, Victoria, Australia. She recently gave birth unexpectedly in a bathroom, despite never knowing that she was pregnant in the first place.

Langmaid and her partner Dan Carty welcomed their new daughter Isla after not realizing they were expecting. The -based model gave birth to her baby girl on a bathroom floor. Langmaid had shown no typical signs of pregnancy. This included no morning sickness, no unusual food cravings, and no baby bump.

In a recent interview, the model said that she was feeling fine up until experiencing an illness right before giving birth. Langmaid also stated she was using birth control regularly. It was only when she went into labor that she knew something wasn't right.

Carty heard her scream from the bathroom and raced to her side. But when he reached her, he quickly realized she wasn't alone. As a matter of fact, she had just given birth.

“I heard a big scream and I ran in there and opened the door and I was worried about her, and then I saw the little one and I thought ‘hang on, there’s two’,” Carty said.

After the model gave birth and her partner learned what had happened, they realized that their baby wasn't breathing. It was actually turning blue in the face. Carty acted quickly and frantically called emergency services.

“We don’t know. We didn’t know she was pregnant. Mother’s OK and the baby is not OK,” Carty explained to the dispatcher.

Langmaid didn't realize she was 37 weeks along with a cryptic pregnancy- better known as stealth pregnancy. This means the mother doesn't know she's pregnant until well into the pregnancy. The possible causes for a cryptic or stealth pregnancy include taking birth control, irregular periods, and low body weight. Polycystic ovary syndrome (PCOS) can also be a cause for cryptic pregnancies.

Another study suggested a possible cause for stealth pregnancies is psychological because the mother isn't ready to accept a pregnancy. The study explains that pregnancy isn't just physical, but also emotional and mental. There are instances that show these factors playing into some cases of surprise cryptic gestation.

Langmaid and Carty have posted on Instagram that baby Isla is healthy despite the minor complications that occurred during delivery. The new mom has received tons of support online from people all over the world. She has posted pictures of her and her growing family and is embracing all the joys of motherhood now. Congratulations to the couple and their baby girl!
