Second trimester

27 Weeks Pregnant

End of the second trimester

This week your baby is around the size of a cauliflower.

How your baby is developing

  • Many reach the end of the second trimester around now.
  • Your baby keeps developing steadily.

What may be happening in your body

  • Heartburn or indigestion can appear or worsen as your growing baby presses up against your stomach.
  • From now on, sleeping on your side is better for your baby than sleeping on your back — pillows supporting your bump and between your knees can help you get comfortable.
  • Your baby's movements are getting stronger, and by now many parents recognise their baby's busier and quieter times of day.

How you may be feeling

  • Reaching the end of the second trimester can bring a sense of progress, alongside nerves about the trimester ahead for some.
  • Broken sleep can leave some people feeling more emotional or on edge during the day.
  • The finish line can feel both close and still far away, and holding excitement and impatience together is common at this stage.

Worth remembering

Broken sleep is common now; short rests through the day can help you cope.

A closer look

Why heartburn shows up now

Pregnancy hormones relax the muscle at the top of your stomach, and your growing baby presses upward, which can push acid back up and cause a burning feeling. It often feels worse after eating or when lying down. Eating smaller meals more often, sitting upright while you eat, and propping up your head and shoulders in bed may help.

Broken sleep in late pregnancy

A bigger bump and general discomfort can make sleep harder to come by now, and sleeping problems are a common symptom at this stage. You may also feel more tired through the day. Napping when you can helps you cope when the night has been disturbed.

Something you can do this week

Noting questions for upcoming appointments can ease your mind.

What comes next

The third trimester ahead brings steady weight gain for your baby — and usually more planning for you.
