How it works
Enter the requested values, check the units, then run the Pregnancy Trimester Calendar Estimate for a copyable informational estimate.
The tool works by counts calendar days from LMP and labels broad ranges; clinical dating may differ. The result is a general estimate that cannot account for every individual factor and does not replace a clinician. Inputs stay in the browser.
