Your short plan for this week

Do now

Review the next eight weeks: scan follow-up, work adjustments, movement guidance, diabetes testing and any recommended vaccines.

Coming up

Ask for plain-language results: what was seen, what was not seen, whether follow-up is needed and who arranges it.

Pause and ask

Do not assume a reassuring scan rules out every later complication; continue routine care and act on new warning signs.

A short checklist

What to do now

  • Review the next eight weeks: scan follow-up, work adjustments, movement guidance, diabetes testing and any recommended vaccines.
  • Stay active in ways that feel stable and are appropriate for your pregnancy.
  • Learn what movement changes should prompt a call later in pregnancy.

Pause and check

What not to do—or what to ask first

  • Do not assume a reassuring scan rules out every later complication; continue routine care and act on new warning signs.

For the support person

One useful thing a partner can do

  • After the scan, compare what each of you heard and write down any unresolved question before details blur.

Contact your care team

Contact your doctor or maternity team promptly

Some concerns need advice before the next routine appointment even when they do not feel like an emergency. If a symptom becomes severe, sudden or frightening, use urgent care instead.
