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:

2. Next, count down 3 calendar months from that date.
3. 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.
