Editorial Policy

Last updated May 1, 2026

Every page on DueDateLab follows a consistent process for choosing sources, verifying claims, and drawing the line between informational content and medical advice. This page explains that process so a reader, a clinician, or an editor can check our work.

Who writes and reviews DueDateLab content

DueDateLab content is produced by a small editorial team operating under a single byline: DueDateLab Editorial. We do this for two reasons. First, we want to keep one consistent voice across the site rather than switching between author personas. Second, we will not invent named clinician credentials we cannot back up. If a real clinician reviews a piece in future, that clinician will be named directly on the page they reviewed.

Each editorial page is written, sourced, and reviewed by the team before publication using the rules below.

How we choose sources

Medical content is sourced from a short list of authorities that match the topic at hand:

We do not source clinical content from open forums, anonymous blogs, lifestyle publications, or aggregator sites that themselves repackage other sources. Where a topic is folklore (for example, the Chinese Gender Chart), we say so plainly and cite the peer-reviewed study that evaluated it.

How we verify medical claims

For each sourced medical claim, our editorial review notes record:

A claim does not appear in published copy until the source has been opened, the quote has been confirmed, and the supporting URL is live. Where a quote in a source contradicts another source, the page either reconciles the difference in plain language or chooses one source explicitly and explains why.

Numerical claims (weeks of gestation, hormone timing, bleeding-pattern thresholds, emergency-routing triggers) are verified against the original source language, not paraphrased from memory. Safety-critical wording (call NHS 111, call 999, contact your maternity unit) stays close to the source's wording rather than being rephrased.

Every medical citation in body copy resolves to the corresponding entry in the page's Sources block. Citation markers are linked superscripts so a reader can move from any sourced sentence directly to the source row.

Review cadence and corrections

Pages are re-checked when the underlying guideline changes, when a sourced URL is reported as broken or moved, or on a scheduled annual review pass, whichever comes first. Each page carries a visible "Last updated" date, and the page's structured data carries machine-readable last-updated and last-reviewed timestamps. If you find a factual error or an out-of-date reference, write to [email protected] and we will correct it.

What this site is not

DueDateLab is informational. It is not a clinic, not a medical provider, and not a substitute for professional care. Every clinical page on the site routes uncertainty back to a qualified clinician (your doctor, midwife, GP, or maternity unit) and includes urgent-care signposting where the topic warrants it. Estimates from our calculators are estimates. The page text helps a reader understand what those estimates can and cannot tell them, then points to the clinical care path for any decision that matters.

Editorial independence

DueDateLab is funded by display advertising and by Amazon Associates affiliate revenue. Our advertising partners do not see article copy before publication and do not influence the editorial decision of which sources we cite, what claims we make, or what safety routing we include. If a sponsored arrangement ever applies to a specific page, that page will carry a clear sponsored-content disclosure at the top.
