Third trimester

29 Weeks Pregnant

Settling into the third trimester

This week your baby is around the size of a butternut squash.

How your baby is developing

  • Movements are often strong now, with their own rhythm.
  • Development continues as your baby grows.

What may be happening in your body

  • A growing bump can make breathing feel tighter — deep breaths get harder as your baby presses up toward your diaphragm.
  • Aches through your back, hips, and pelvis can build, and you may tire more by the end of the day.
  • A comfortable sleeping position gets harder to find, and heartburn or frequent trips to the loo can break up the night.

How you may be feeling

  • As the third trimester begins, excitement and tiredness can grow at the same time.
  • You may want to start getting ready while also wondering, 'will I manage to get everything done?'
  • Your baby's strong movements can pull you closer, even as uncertainty about the birth surfaces now and then.

Worth remembering

Strong, regular movement is a good sign; you know your baby's pattern best.

A closer look

Why breathlessness happens now

In the third trimester it's common to feel more breathless, as your growing baby presses up against your lungs and you're carrying more weight. You may notice it most when you're active or climbing stairs. It can feel uncomfortable, but it's an expected part of this stage.

Aches, and what can ease them

The extra weight you're carrying puts a strain on your lower back and pelvis, so aches often build as the day goes on. Getting enough rest — especially later in pregnancy — and a warm bath can help ease the muscles for some people.

What comes next

You reach three-quarters of the way over the next week.
