38 weeks pregnant

The baby is at term and could be born at any moment, but each day still brings more maturation. The focus is on following movements, well-being and the signs of labor.

Quick read

  • The lungs, brain and nervous system keep refining their functions.
  • The baby may be engaged in the pelvis.
  • Contractions may become more organized as birth approaches.
Fetal development

How your baby is doing this week

The body is rounder and most of the lanugo is already gone. The nervous system keeps maturing. The position tends to be more stable, although the care team confirms the presentation and the conditions for birth.

Body and routine

What may change in your body

Pelvic pressure, trouble sleeping, frequent trips to the bathroom and vaginal discharge may increase. Contractions may come and go until a labor pattern is established.

Possible steps

Care for this week

  1. Rest and eat regularly; you don't need to 'speed up' labor.

  2. Follow the agreed plan for your waters breaking, bleeding and contractions.

  3. Keep paying attention to movements.

Prenatal care focus

  • Monitoring remains weekly, or more frequent if needed.
Twin pregnancy

If you're expecting twins

If it is a twin pregnancy that is still ongoing, follow the team's plan strictly — the birth window is usually different from that of a single pregnancy.

Support network

For those by your side

Avoid filling the calendar with visits. Save energy and availability for the birth.

Common questions

Questions for this week

Do the waters always break before contractions?

No. Labor can start with contractions, and the waters can break before or during the process.

Can I stay at home with contractions?

It depends on the pattern, your waters, any bleeding, movements, distance from the maternity hospital and your care team's advice.

When to seek care

  • Fluid leaking from the vagina, especially in a gush or a continuous trickle, needs to be evaluated.
  • Once movements have become familiar, a significant decrease in the pattern you notice should be evaluated without waiting until the next day.
  • After 20 weeks, a severe/persistent headache, vision changes, severe pain in the upper abdomen or sudden swelling deserve evaluation for a possible hypertensive condition.

In an emergency, go to the urgent care service in your area. This content does not replace a professional assessment.
