FAQ
How accurate are due dates?
Only about 4% of babies arrive exactly on the estimated date; most are born within two weeks of it.
What is Naegele's rule?
Add 280 days (40 weeks) to the first day of the last period, adjusting for cycle length if it differs from 28 days.
Why does cycle length matter?
Ovulation happens about 14 days before the next period, so longer cycles shift conception and the due date later.
