The formula for calculating the gestation period based on the menstrual cycle
The formula that is commonly used to calculate pregnancy based on the menstrual cycle was invented by Franz Karl Naegele, an obstetrician from Germany who lived in the 19th century. Although there are drawbacks because it can only be used by mothers with a menstrual cycle of 28 days, there is no harm in trying it. The method:
- First, determine the first day of your last menstrual period
- Next, count down 3 calendar months from that date.
- Finally, add 1 year and 7 days to the date.
For example, your last menstrual period started on February 9, 2022. Then count down the calendar to three months before February, which is November 9, 2022. Then add 1 year and 7 days, you will arrive on November 16, 2023, as your estimated HPL period.
This 3-step method is known as the Naegele formula and is based on a normal 28-day menstrual cycle. Therefore, your gestational age may have to be adjusted for a longer or shorter menstrual cycle.
