The longest recorded human pregnancy lasted 375 days, or just over 12 months. This remarkable case involved Beulah Hunter, who gave birth to her daughter, Penny Diana, in February 1945. While a typical pregnancy lasts around 280 days (approximately 40 weeks or 9.5 months), Hunter's pregnancy extended well beyond the normal timeframe, making it the longest documented pregnancy. Pregnancies lasting 42 weeks (around 10 months) are relatively common, however.
Understanding Pregnancy Length
The average pregnancy duration is widely accepted to be 40 weeks, calculated from the first day of the woman's last menstrual period. However, there's natural variation, and some pregnancies go longer or shorter than this average.
- Typical Range: Most pregnancies fall within a range of 37 to 42 weeks.
- Post-Term Pregnancy: A pregnancy exceeding 42 weeks is classified as post-term.
While Beulah Hunter's pregnancy is exceptional, it highlights the variability in human gestation. The medical community continues to study the factors that contribute to longer or shorter pregnancy durations.
Several sources corroborate the 375-day pregnancy of Beulah Hunter as the longest recorded:
