    How to use the Pregnancy Timeline

    1. Enter start from, date.
    2. Select any method, activity level or option shown on this page, then choose Calculate.
    3. Read the main result together with the supporting values, method, assumptions and limitations below before using the estimate.

    How this calculation works

    Pregnancy timeline settings remain on-device and can be reset locally. Pregnancy dating uses standard LMP, conception or IVF date conventions. Clinical ultrasound and clinician assessment can revise a working due date.

    Method transparency: Results are calculated from the values you enter. Health estimates are educational reference values, not diagnoses or treatment advice.

    Example calculation

    The sample values loaded into the calculator produce 0w 0d. This example exists to show how the output is structured; replace the sample values with your own inputs for your calculation.

    Assumptions and limitations

    • Pregnancy dating is an estimate and clinical ultrasound may change the working due date.
    • This tool is educational and does not replace prenatal care or medical advice.

    Sources and review status

    Source set last verified 2026-09-25. No clinician review is claimed unless a real named reviewer is displayed.
