Getting ready for the outside
Most babies settle into a head-down position sometime this month, preparing for birth, though there's still time for that to change. Bones are hardening everywhere except the skull, which stays flexible to ease the trip through the birth canal. Movements may feel different — less sharp kicking, more pressing and stretching — simply because there's less room left to move freely.

What's developing right now
Bones harden throughout the body, though the skull stays soft and flexible for birth.
Continue producing surfactant, a substance that helps the air sacs stay open after the first breaths.
Keeps growing quickly, with increasing coordination between movement and sensory response.
Receives antibodies passed from the parent through the placenta, offering some early protection after birth.
What your body is doing
- Braxton Hicks contractions may become more frequent and noticeable.
- Sleep can be increasingly disrupted by discomfort and frequent bathroom trips.
- The bump often drops slightly as the baby moves into position, easing breathing a little.
- Swelling in the ankles and feet is common, especially with long periods of standing.
Eating for this month
Energy needs are near their highest now, supporting rapid weight gain in the baby during these final weeks. Iron and calcium remain important, and staying well hydrated can help with the swelling and constipation common late in pregnancy. Smaller, more frequent meals usually continue to work better than large ones.
Checkups commonly done this month
- Growth ultrasounds to check the baby's size and position, if recommended — schedules vary by country and doctor
- A discussion of birth preferences and plans with a doctor or midwife
- Blood pressure and urine checks at increasingly frequent prenatal visits
Contact your doctor promptly if…
Regular, strengthening contractions before 37 weeks
A sudden decrease in movement compared to the baby's usual pattern
Severe headache, vision changes, or swelling that appears suddenly
Leaking fluid or bleeding
Questions people ask
What if the baby isn't head-down yet?
There's still time. Many babies who aren't head-down at this stage turn on their own before labor begins, since there's more room to move in month eight than closer to full term. A doctor can discuss options if the baby is still in a different position as the due date nears.
Why are prenatal visits more frequent now?
Doctors typically increase visit frequency in the third trimester to monitor blood pressure, growth, and the baby's position more closely, since most complications that need prompt attention tend to emerge in these final weeks. It's a routine step up in monitoring, not a sign that anything is wrong.
