How do I track my pregnancy week by week?

Bottom lineTrack your pregnancy week by week from your due date (about 40 weeks from your last period or an early scan): count your current week and trimester, then follow your baby's development, changing symptoms, and the schedule of antenatal appointments and screening tests; keep taking supplements, and contact your clinician straight away for bleeding, severe pain, or reduced movements rather than waiting.

Tracking your pregnancy by week helps you follow your baby's development, anticipate symptoms, and keep up with appointments and tests. It all starts from your due date.

Get your starting point

1. Find your due date (about 40 weeks from your last period, or from an early scan)
2. Count back to know which week you're in now
3. Note your trimesters: first (weeks 1 to 12), second (13 to 27), third (28 to 40)

What to follow each week

• Baby's development - size and milestones
• Your symptoms - and how they change by trimester
• Appointments and screening - antenatal visits, scans, and blood tests
• What to prepare - from supplements early on to birth plans later

Stay on top of care

• Attend all antenatal appointments
• Keep taking recommended supplements like folic acid and vitamin D
• Note any symptoms to report between visits

When to call sooner

Don't wait for the next milestone if you have bleeding, severe pain, reduced baby movements (later on), or other warning signs - contact your clinician straight away.
