34 Weeks Pregnant: What to Expect This Week
Thirty-four weeks pregnant and the lungs are close to fully mature. Baby sleeps 16–18 hours a day and you may notice quieter periods in movement — this is normal.

Baby's Development at 34 Weeks
The lungs are nearly fully mature — a baby born at 34 weeks has an excellent prognosis and usually needs only brief support. The central nervous system has matured significantly. Fat stores continue to build, and baby is gaining around 200–250g per week. The skin has become smooth and chubby-looking. Baby may be settling into a head-down position if they haven't already. The vernix coating remains, protecting the skin until after birth.
Your Body at 34 Weeks Pregnant
Lightening (baby engaging into the pelvis, also called "dropping") happens for some people around 34–38 weeks — you may notice slightly easier breathing but increased pelvic pressure. Symphysis pubis pain (a sharp, stabbing pain at the front of the pelvis) is common. Braxton Hicks contractions are frequent and can be convincingly contraction-like. Tiredness is profound.
Tips for Week 34
- Install the car seat and have it checked by a certified installer.
- Write your birth plan in final form and share it with your hospital.
- If baby is breech at this stage, ask your provider about ECV (external cephalic version) — it's most effective at weeks 36–37.
- Start perineal massage from around week 34 — research shows it reduces tearing during delivery.

Frequently Asked Questions
What happens if I go into labour at 34 weeks?
A baby born at 34 weeks (called "late preterm") is generally considered to have an excellent outlook. They may need some time in a special care nursery for breathing support, temperature regulation, and feeding, but serious complications are much less common than at earlier gestational ages. Most 34-weekers go home within 1–3 weeks.
What is perineal massage and does it work?
Perineal massage involves gently stretching the tissue between the vagina and anus (perineum) in preparation for the stretching that occurs during delivery. Studies show that starting from 34–35 weeks and massaging for 5–10 minutes 3–4 times per week significantly reduces the likelihood of perineal tearing and episiotomy in first-time parents.
