About DueDate.Baby | UK Pregnancy Planning Tool

DueDate.Baby is an independent UK pregnancy planning site designed to make pregnancy dates and milestones easier to understand.

Pregnancy is filled with dates, weeks, scans, and appointments. Our goal is to help parents estimate their due dates, understand what pregnancy week they are currently in, and plan around common milestones such as trimesters, 12-week and 20-week scans, and maternity leave preparation.

Our UK Focus

We know that maternity care differs around the world. That's why DueDate.Baby is built specifically with the UK in mind. Our timelines and week-by-week guides align with standard NHS maternity schedules, ensuring the milestones you see reflect what you can expect from your midwife and local maternity team.

How We Handle Pregnancy Information

We use official NHS and GOV.UK guidance as the starting point for UK care and maternity planning information. Health-adjacent pages show their direct sources and the date that source set was last checked. We explain calculator assumptions in plain language and update affected pages when cited guidance changes.

DueDate.Baby is independent and does not provide clinical care, diagnoses, treatment recommendations, or personalised maternity or employment advice. Read our editorial policy for the full review process.

Not Medical Advice

Please note: DueDate.Baby is a planning tool, not a medical service. The information and calculators on this site provide estimates based on standard clinical guidelines (such as calculating 280 days from the first day of your last menstrual period).

It should neverreplace guidance from a midwife, GP, NHS service, or qualified healthcare professional. Pregnancy dates are estimates and will likely change after you have your dating scan. If you are worried about any symptoms, have questions about your baby's development, or need urgent advice, please contact your maternity team or NHS 111 immediately.
