Honestly, the idea of being pregnant for more than nine months sounds like a special kind of endurance test. Most of us grew up hearing that pregnancy is a 40-week gig. You count the days, you buy the tiny socks, and by week 39, you’re basically a human balloon just waiting to pop. But biology isn't always a fan of the rules. Sometimes, it decides to take the scenic route.
If you've ever wondered about the absolute limit of human gestation, you’re going to find the story of Beulah Hunter fascinating. Or maybe terrifying.
What is the record for the longest pregnancy ever?
In 1945, a 25-year-old woman in Los Angeles named Beulah Hunter gave birth to a healthy baby girl. That doesn't sound like a headline until you look at the calendar. According to her doctor, Daniel Beltz, Beulah was pregnant for 375 days.

That’s over a year. 12 and a half months, to be precise.
To put that into perspective, the average pregnancy lasts about 280 days. Beulah blew past that by nearly a hundred days. When her daughter, Penny Diana, was finally born, she didn't weigh 20 pounds like you might expect from a "toddler" in the womb. She weighed a perfectly normal 6 pounds and 15 ounces.
Why did it take so long?
Dr. Beltz had a theory that sounds kinda wild today. He claimed the pregnancy was legit because he had a positive pregnancy test for Beulah from March 1944. She didn't give birth until February 1945. His explanation? The baby simply developed at an incredibly slow rate.
While most babies are hitting milestones like a heartbeat at week five or six, Penny Diana reportedly took her sweet time. Dr. Beltz noted an "apparent cessation of growth" early on. He didn't even hear a fetal heartbeat until September, which is way later than the usual 10-12 week mark.
The controversy: Was it actually 375 days?
Medicine in 1945 wasn't what it is today. We didn't have high-resolution ultrasounds or sophisticated blood panels to track everything to the hour. Because of that, some people are—rightfully—skeptical.
The main argument against the record is the "miscarriage theory." Skeptics suggest Beulah might have been pregnant, lost the baby early on, and then conceived again almost immediately without having a menstrual period in between. In a time before routine scans, a doctor might easily have assumed it was one continuous pregnancy.
However, Dr. Beltz was adamant. He called the idea of a second pregnancy "quite impossible." He staked his professional reputation on the fact that this was one long, slow-motion marathon of a pregnancy.
Other "marathon" pregnancies in history
Beulah isn't the only one who didn't get the memo about the nine-month deadline. There are other stories floating around, though many are more legend than medical fact.
- Wang Shi (2015): A woman from China's Hunan province claimed to be pregnant for 17 months. Doctors were skeptical because her placenta and the baby's development didn't match the timeline, and she eventually had a C-section in her 18th month.
- Jackie Chan: Yeah, the action star. He has claimed in interviews that his mother carried him for 12 months. He was reportedly a massive baby, weighing 12 pounds at birth.
- The "Ten Month Mamas": In some communities, women have reported pregnancies lasting up to 44 or 45 weeks without medical intervention.
The science of "Post-term" pregnancies
Today, doctors usually won't let you get anywhere near the 375-day mark. Once you hit 42 weeks, you’re officially in "post-term" territory. At that point, the placenta—which is basically the baby’s life-support system—starts to age. It doesn't work as well as it used to.
Medical professionals usually suggest induction between 41 and 42 weeks to avoid complications like:
- Macrosomia: The baby getting too big to be delivered safely.
- Meconium aspiration: When the baby passes their first stool in the womb and breathes it in.
- Low amniotic fluid: Which can cause the umbilical cord to get pinched.
A study published in The New England Journal of Medicine indicates that while natural variation exists, the risk of stillbirth begins to rise significantly after the 42-week mark. This is why the record-setting cases of the past are so rare now; we simply don't let it happen for safety reasons.
How to handle an overdue pregnancy
If you find yourself staring at a past-due date, don't panic. You aren't likely to break Beulah's record. Most "overdue" babies are just waiting for the right hormonal signal to start the show.
What you can actually do:
- Trust the scans: Early ultrasounds are much more accurate than "last period" dates. If your 8-week scan said one thing and your period said another, the scan is usually right.
- Do your kick counts: If you're past 40 weeks, pay extra attention to movement.
- Talk about induction: Ask your OB-GYN or midwife about their specific "post-dates" protocol. Many will start more frequent monitoring (like Non-Stress Tests) once you hit 41 weeks.
- Movement helps: Curb walking, prenatal yoga, and staying active can sometimes help the baby's head engage and get things moving.
Beulah Hunter’s 375-day record remains a bizarre footnote in medical history. Whether it was a biological fluke or a tracking error, it serves as a reminder that the human body is unpredictable. While you're likely to meet your baby long before the one-year mark, it's always worth remembering that "due dates" are really just "due windows."

If you’re currently past your due date, your next step should be to schedule a biophysical profile or a non-stress test with your provider. These checks ensure the placenta is still doing its job and the baby is happy while you wait for labor to start naturally.
