My Pregnancy Journey
Add your pre-pregnancy weight & height for a gain range
How this page is calculated
My Pregnancy Journey is a convenience view, not a separate calculator — it takes the one due date or last-period date you enter and runs it through the same math as three of our individual tools at once: the 280-day (40-week) gestational dating behind the Due Date Calculator and Pregnancy Wheel, the week-to-month mapping behind the Weeks to Months Calculator, and, if you add your pre-pregnancy weight and height, the BMI-based IOM weight-gain ranges behind the Weight Gain Calculator.
Nothing here is calculated differently from those standalone tools — it's the same formulas, just displayed together so you don't have to re-enter your dates on three separate pages.
Things to know
Because this page recalculates from scratch each time you press the button, your results reflect today's date against the due date or last period you entered — nothing is saved to a server, though your device can remember your past entries locally via the "past calculations" feature below the form.
The same caveats that apply to each individual calculator apply here too: due-date math is an estimate (only around 5% of babies arrive on their exact due date), and weight-gain ranges are general guidance that your own care provider will tailor to you. If you'd like more detail or context on any one figure, the links on each card above take you to the full standalone calculator and its explanation.
The weight-gain card is optional by design — it only appears once you've entered a pre-pregnancy weight and height, since that's what a BMI-based range needs to be calculated. If you're expecting twins or another multiple pregnancy, use the standalone Weight Gain Calculator instead, since this page's quick view only covers singleton ranges.
Why we built a combined view
Many people tracking a pregnancy end up checking the same handful of numbers over and over — current week, due date, trimester, and whether their weight gain is roughly on track — often on different pages or apps. This page exists to put those in one place from a single date entry, so you don't have to re-enter your due date or last period three separate times to see three related answers.
It's meant as a quick daily or weekly check-in rather than a replacement for prenatal care — think of it as a companion view alongside your appointments, not a diagnostic tool.
