The Longest Recorded Pregnancy

Have you ever wondered what the record for longest pregnancy is? If so, we have the answer for you! According to Guinness World Records, the longest recorded pregnancy ever was 375 days!

Facts About the Record

When it comes to the longest known pregnancies, there is a lot to learn. Here are some key points on the 375 day pregnancy:

  • Date: The pregnancy happened in 1945.
  • Mother: Beulah Hunter was the mother of this record-breaking baby.


  • Child: Beulah’s baby weighed 7 pounds, 8 ounces, and was named Penny.

The Reason for the Lengthy Pregnancy

The reason for the very long pregnancy was due to a condition known as post-term pregnancy. At the time of delivery, doctors determined that the infant was healthy and had no birth defects.

Other Long Pregnancies

Just because Beulah Hunter holds the world record doesn’t mean that other long pregnancies haven’t happened. Here are a few other lengthy pregnancies that have made headlines:

  • In the late 1800s, a young woman in Kentucky experienced a 278-day pregnancy.
  • In 2010, an American woman gave birth after a 266-day pregnancy.
  • In 2013, a mothers water broke after 300 days.

The Average Length of a Pregnancy

The average length of time a woman is considered to be pregnant is 280 days, or 40 weeks. However, due to a variation in individual hormones, the length of time a woman is truly pregnant can fluctuate. Medical researchers believe that this hormone variability is responsible for some of the extra long pregnancies reported today.

While it is true that a few very long pregnancies have been reported in modern medical history, the longest recorded pregnancy still holds true for Beulah Hunter and her daughter Penny!
