Sources & medical-review policy
Pregnancy is a health topic, so the information here has to be right and clearly sourced. This page explains where our facts come from, how we keep the tone careful and neutral, and the corrections we made when rebuilding the original site.
Where our information comes from
For every week and topic we rely on primary, reputable medical authorities rather than secondary blogs — professional bodies, national health services, and major medical institutions. Development sizes and timelines are given as typical ranges, because every pregnancy is different. Our main sources include:
- ACOG — Pregnancy (FAQ / month-by-month)
- ACOG — How to Tell When Labor Begins
- ACOG — Nutrition During Pregnancy
- ACOG — Special Tests for Monitoring Fetal Health
- CDC — Folic Acid
- CDC — During Pregnancy
- NHS — Keeping well in pregnancy
- NHS — How can I work out my due date?
- NHS — Signs that labour has begun
- Mayo Clinic — Fetal development: The 1st trimester
- Mayo Clinic — Fetal development: The 2nd trimester
- Mayo Clinic — Fetal development: The 3rd trimester
- MedlinePlus (NIH/NLM) — Prenatal Care
Informational only — not medical advice
Everything on this site is general educational information. It is not medical advice and is not a substitute for care from your own doctor, midwife, or qualified provider. We avoid definitive directives and personalised dosing, and we route anything urgent to a clear ‘contact your provider’ callout. In an emergency, contact your maternity unit or local emergency number.
How we handle uncertainty
Where evidence is limited or claims are popular but unproven, we say so rather than repeat them. For example, there is no good scientific evidence that particular sexual positions improve the chance of conceiving, so we do not present that as fact.
Corrections we made to the original site
- Dated medical claims updated. The original 2000s-era copy has been rewritten against current guidance from ACOG, the NHS, Mayo Clinic, and MedlinePlus.
- Folic acid reframed. General guidance (about 400 micrograms a day, ideally before conception) is presented as information, with the dose and timing to be confirmed with a provider — not as a personal prescription.
- Emergency framing tightened. Topics such as a suspected amniotic-fluid leak now route clearly to prompt professional assessment rather than casual self-management.
- Unsupported content removed. The original ‘sexual positions for conception’ page (no scientific basis) was removed; its link now points to a neutral conception guide.
