38 Weeks Pregnant: What to Expect This Week
Thirty-eight weeks pregnant — baby is shedding the vernix and swallowing it along with amniotic fluid, creating the first bowel movement (meconium) that will appear after birth. Any day now.

Baby's Development at 38 Weeks
Baby is shedding the remaining vernix and swallowing it — this, combined with shed lanugo and intestinal secretions, forms meconium. The brain and neural connections continue to develop and will continue to do so for years after birth. Baby's lungs are fully mature. The sucking reflex is well-practised. Nails have grown beyond the fingertips and may need trimming after birth. Baby is perfectly ready.
Your Body at 38 Weeks Pregnant
Many people feel a mix of impatience and anxiety at this point. Pre-labour symptoms can appear and disappear over days: irregular contractions, mucus plug loss, loose stools, and the feeling that something is about to happen. Some people feel an unusual burst of energy just before labour begins. Sleep is challenging. Backache, pelvic pressure, and general discomfort are significant.
Tips for Week 38
- Stay busy but rest well — distraction helps the final waiting period pass faster.
- Keep your phone charged and ringer on.
- Make sure your partner knows the plan and has everything they need.
- Know when to call: 5-1-1 contractions, broken waters, reduced movement, heavy bleeding, or any concern.

Frequently Asked Questions
What is meconium and is it dangerous?
Meconium is baby's first bowel movement — a dark, tar-like substance made up of amniotic fluid, lanugo, mucus, and intestinal cells. It normally passes in the first day or two after birth. If it's passed into the amniotic fluid before birth (meconium-stained waters), your care team will monitor closely and may recommend specific precautions during delivery to prevent meconium aspiration.
How long does early labour last for first-time parents?
Early labour (latent phase) — from the onset of regular contractions to 6cm dilation — averages 6–12 hours for first-time parents but varies enormously. Some people have a latent phase lasting 24–48 hours; others move quickly. The best approach during early labour is to stay home, rest, eat lightly, and distract yourself until contractions are regular (5-1-1 rule) or your waters break.
