About Pregnancy Week to Week

Pregnancy Week to Week is a free, independent educational reference that follows pregnancy week by week, from week 1 to week 40, alongside plain-language guides to common questions. It began as a small pregnancy microsite and has been rebuilt as a sourced, carefully reviewed reference.

Because pregnancy is a health topic, accuracy matters. Every page is grounded in reputable medical authorities — the ACOG — Pregnancy (FAQ / month-by-month), the NHS — Keeping well in pregnancy, Mayo Clinic — Fetal development: The 1st trimester, and MedlinePlus (NIH/NLM) — Prenatal Care — and figures are given as typical ranges, not guarantees. See our sources & medical-review policy for how we do this and the corrections we made to the original site.

This site is informational only and is not medical advice. Always consult your own doctor, midwife, or qualified healthcare provider about your pregnancy. Pregnancy Week to Week is an independent publisher operated by VentureCorp, Inc. Have a correction? Contact us.
