Third trimester

35 weeks pregnant

The fetus is around the size of a honeydew melon. Weight gain is rapid, roughly 250g a week, and the brain is developing quickly in these final weeks.

Your baby at 35 weeks

The brain grows substantially in the last weeks of pregnancy, which is one reason going to term matters even when the lungs are ready.

Kidneys are fully developed and the liver is processing waste. Most physical development is complete; the remaining work is growth and maturation.

The fetus is likely head-down and may begin to engage, dropping into the pelvis.

How you may be feeling

If the baby engages you may find breathing easier but pelvic pressure and urinary frequency worse. This is sometimes called lightening.

Appointments typically become weekly from around now, with closer monitoring of position, growth and blood pressure.

Common symptoms around week 35

  • Pelvic pressure increasing
  • Easier breathing if the baby has engaged
  • Frequent urination
  • Braxton Hicks
  • Difficulty sleeping

Appointments and tests around now

Group B strep screening is commonly offered between weeks 35 and 37. If positive, antibiotics during labour are usually recommended.

What is normal, and what varies

Engagement timing varies hugely. First babies often engage a few weeks before birth; subsequent babies frequently do not engage until labour. Neither predicts when labour starts.

Worth doing this week

Finish everything this week if you can

Bag, car seat, contact numbers, notes. From here it is reasonable to assume labour could start at any point.

Rest when you can

Energy reserves matter for labour. This is not the week to catch up on projects.

Talk through the plan with whoever is supporting you

They should know what you want and who to call, so you are not directing logistics in labour.

Looking ahead

Next week the baby is nearly term and position becomes clinically important.
