Direct guidance
What to know or do
Ask what question the scan is meant to answer and whether a repeat may be needed if it is too early for a definite result. A clinician-provided due date should remain the timeline baseline unless the care team changes it.
What changes the answer
- Whether this is screening, diagnosis, monitoring, treatment or birth planning
- Pregnancy week, previous results and what the result could change
- Benefits, limits, alternatives, follow-up and the time available to decide
Check with your care team
When to get individual help
Check the exact item or situation with a doctor, midwife, pharmacist or relevant clinician; the name of a broad category is not enough for a personal decision.
