Sıkça Sorulan Sorular

Why is conception estimated at 14 days after the LMP?
Ovulation typically occurs around day 14 of a standard 28-day cycle, so conception is estimated near that point.
Is this accurate for irregular cycles?
This estimate assumes an average cycle length; if your cycles are irregular or longer/shorter than 28 days, actual conception timing may differ.
What inputs does the Pregnancy Conception Calculator need?
You'll need to provide: First day of last period. All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
