Private maternity visit preparation
Antenatal appointment date planner
Start with the estimated due date confirmed by your maternity team, or make a provisional estimate from the first day of your last period. Then map the WHO routine contact weeks to calendar dates for discussion with your local clinic.
Dates must not delay care
Contact a maternity service urgently for bleeding, severe or persistent abdominal pain, a severe headache or vision change, fluid leakage, breathing difficulty, or a change in your baby's usual movements. Use local emergency services if the situation is life-threatening.

Questions this planner answers carefully
Why prefer a maternity-team due date?
A date based only on the last period assumes a known, regular cycle. A maternity team can consider ultrasound dating and clinical history. Use their documented date as the working date when available.
Is the 37- to 42-week range a prediction of labour?
No. It shows the calendar span corresponding to 37 through 42 weeks from the calculated LMP basis. It does not predict when labour will start or whether waiting is safe.
Does every pregnancy use these eight dates?
No. The WHO schedule is a general routine model. Local protocols, availability, symptoms, scan results, multiple pregnancy and health history can change timing and frequency.
