What's Happening With Your Baby
The baby is preparing for birth. The rib cage is defined. There's enough fat tissue to maintain body temperature. The brain and nervous system are still developing.
What's Changing For You
Sleep is genuinely difficult now. Swelling, cramps and frequent contractions have become daily. Impatience is normal.
To Do This Week
Time your contractions: every 5 minutes, lasting 1 minute, continuing for 1 hour means it's time for hospital.
If your waters break, note the colour and the time and call your doctor immediately.
Prioritise rest; this is the week for banking energy.
Frequently Asked Questions
How many months is 38 weeks pregnant?
Week 38 of pregnancy falls in month 9 and in the third trimester. Pregnancy months don't run in neat four-week blocks, so the week-to-month conversion rarely lands on a whole number — which is why pregnancy is tracked in weeks.
How big is the baby at 38 weeks?
At 38 weeks your baby is roughly the size of a leek: around 49.8 cm long and 3083 grams. These are averages; clear variation between babies is normal, and what matters is the growth curve your doctor is tracking.
How long is left at 38 weeks pregnant?
Assuming a 40-week pregnancy, you have around 2 weeks left at week 38. Most births happen between weeks 37 and 42, so a due date is a range rather than a fixed day.
What should I watch out for at 38 weeks?
Time your contractions: every 5 minutes, lasting 1 minute, continuing for 1 hour means it's time for hospital. If your waters break, note the colour and the time and call your doctor immediately. Prioritise rest; this is the week for banking energy.

When To Seek Care Immediately
Whatever week you are in, contact your doctor or the nearest health facility without waiting if you have: vaginal bleeding or fluid loss, severe persistent abdominal pain, a severe headache, blurred vision or flashing lights, sudden swelling of the hands or face, a fever above 38 °C, burning on urination with fever, persistent vomiting, fainting, or — after week 28 — a clear reduction in your baby's movements. In these situations reach real medical care rather than an app or a web search.
