  1. New guides

    Four guides to help you make sense of pregnancy dates

    Follow the Pregnancy Calculator walkthrough with worked examples, then explore why different records can show different dates or week counts.

    • Separate guides cover gestational age and age since fertilization, due dates from ultrasound and the last period, and counting weeks after IVF transfer.
    • All four guides are available in the five site languages. The Visual Library collects the illustrations and links back to the articles.

  2. New tool

    Meet the Pregnancy Calculator

    Estimate your due date and completed weeks and days using the dates or report you already have. You can try a fictional example before entering your own information.

    • Choose from six methods, including the last period, an ultrasound report, IVF transfer details, or a due date documented by your clinician.
    • Explore milestones and weekly development. The tool explains how it reached the estimate and which growth figures come from population references.

  5. Site change

    More reliable page loading after site updates

    A page left open through a site update could still look for older files and lose its styling. PeriodlyWise can now recover when those files are unavailable.

    • The site tries again with the latest styles and interactive files for the page you’re viewing.
