Five first steps
- Note the first day of your last period and whether cycles are usually regular.

- Keep reports and share relevant information with Askabide and Osakidetza.
When to have the first ultrasound
The value of ultrasound depends on gestational age and the reason for assessment. At a very early stage only part of the expected development may be visible and a repeat scan may be needed.
Severe pain, significant bleeding, dizziness, fainting or risk factors should not wait for a routine scan.
