How is the due date calculated?
A typical pregnancy is estimated to last about 40 weeks,
or 280 days, from the first day of the last menstrual period.
If your menstrual cycle is longer or shorter than 28 days,
the estimate can be adjusted based on the cycle length you enter.
The estimated conception date is approximately two weeks
before the end of the first trimester and may vary between
individuals.
