FAQs
Which method should I use—LMP or Conception Date?
LMP is most commonly used because many people don’t know the exact conception date.
What if my cycle is not 28 days?
Use the cycle length slider to match your average cycle for a more accurate estimate.
Is the due date guaranteed?
No—due dates are estimates. Many babies arrive a bit earlier or later.
