The two sources under the weekly pages
The measurements — the centimetres and inches printed beside every drawing — come from a published fetal-development reference table. The developmental and symptomatic material comes from the UK National Health Service’s pregnancy week guides. Both are linked at the foot of every week page, by name, so a reader can check us rather than trust us.
Where a week has no reliable measurement, we print none. Weeks one to three are dated from before conception and make no size claim at all; week four’s clinical source describes the embryo as approximately the size of a pinhead and gives no figure, so neither do we. A comparison invented to fill a gap is worse than an empty space.
The flower is a comparison, not a measurement
Every week is drawn as a botanical at the baby’s true scale — and the real measurement is always printed next to it. That pairing is a rule. A size comparison on its own asks to be believed; a comparison with the number beside it can be verified. This is the single difference between this site and every fruit-comparison chart on the internet.
What “not reviewed by a clinician” means
It means exactly what it says. Nobody with a clinical credential has read these pages. Citing the NHS is not the same as being reviewed by a midwife, and a page that cites good sources while implying medical review is doing something dishonest in a category where dishonesty has consequences.
So the note sits on every page carrying health content, and the structured data behind those pages deliberately omits the reviewedBy and lastReviewed properties that search engines and answer engines read as a review signal. Both go in the day a named clinician actually reviews a page — with their name and credential printed on it, and the date — and not one day earlier.

How AI is and is not used
The weekly corpus was drafted with AI assistance and then edited, sourced and fact-checked by a person against the two references above. Nothing is published because a model produced it. Where a model produced a claim we could not tie to a source, the claim was cut rather than softened.
Inside the app, the Ask feature is answered by AI under a safety policy: ordinary questions get direct answers, and a fixed list of urgent topics always returns guidance to seek care rather than an answer. Answers are marked in words — everyday, or worth mentioning — and never with a percentage, because a number attached to a medical judgement is a precision nobody has.
What we will not publish
- Any statement we cannot tie to a named, linkable source.
- A measurement, milestone or symptom presented as universal when the clinical literature gives a range.
- Risk scores, percentages of certainty, or anything shaped like a diagnosis.
- Content generated at scale to occupy search results. Every one of these forty pages carries material a template cannot produce — its own measurement, its own drawing, its own sourced prose. If a week ever had nothing but the number swapped, it would not ship.
- Invented reviews, ratings, testimonials, or press mentions.
Corrections
If something here is wrong, tell us and we will fix it. Write to support@zohrababy.com with the page and what is wrong with it. Substantive corrections to health content are made to the page and noted on it. We would rather be corrected in public than be quietly wrong.
