Your short plan for this week

Do now

Choose one sleep or reflux adjustment to test for several nights, such as earlier smaller meals or upper-body support.

Coming up

Bring symptoms that interrupt eating or sleep to the next visit; ask what treatments are available rather than assuming you must tolerate them.

Pause and ask

Do not take new indigestion or sleep products without checking pregnancy suitability and interactions.

Baby’s development this week

Muscles and lungs continue maturing while the brain builds new connections.

Plain-language examples

What this means in real life

Breathlessness with stairs can increase gradually; sudden breathlessness, chest pain, blue lips or difficulty speaking is not routine discomfort.

  • Choose one sleep or reflux adjustment to test for several nights, such as earlier smaller meals or upper-body support.
  • Discuss birth preferences, feeding support and early recovery.

One useful thing a partner can do

  • Protect a rest window, handle late chores and avoid minimizing exhaustion because the birth is still weeks away.

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.
