Please read — this is a date estimate, not medical advice
Your due date is an estimate, not a fixed date — a dating scan may give a different result. Babbez does not provide medical or pregnancy-care advice. For your confirmed due date, antenatal care, what "full term" means for you, and any questions or concerns, follow your doctor, midwife, or obstetrician and a qualified authority such as the NHS (UK) or the ACOG / AAP (US).
