Third trimester

28 Weeks Pregnant

Into the third trimester

This week your baby is around the size of an aubergine.

How your baby is developing

  • Around now many parents enter the third trimester.
  • Your baby is gaining weight and tends to move more.

What may be happening in your body

  • With movements now well established, getting to know your baby's usual pattern helps you tell what's normal for them day to day.
  • Swelling in your ankles, feet or fingers can appear, usually building up toward the end of the day.
  • Your back is under more strain from the extra weight you're carrying, and your joints and ligaments are looser than usual.

How you may be feeling

  • Stepping into the third trimester can feel like a real shift, bringing relief, disbelief or a fresh wave of nerves for different people.
  • As pregnancy becomes more physical, some people feel their patience with everyday tasks wearing thinner, which is understandable.
  • Getting to know your baby's movements can bring a steady sense of connection for some, day by day.

Worth remembering

Keep noticing your baby's movements; if the pattern changes, contact your midwife promptly.

A closer look

Getting to know your baby's movements

By the third trimester your baby's movements usually settle into a pattern that becomes familiar to you — the times they tend to be active and the times they rest. There's no set number of movements you need to count; what matters is what's usual for your own baby. Knowing their normal pattern now is something you build gradually, day by day.

Swelling as the day goes on

Your body holds more water in pregnancy, and your growing womb can slow the blood flow back up from your legs, so mild swelling in your ankles, feet or fingers is common — usually worse by the end of the day. Putting your feet up when you can, avoiding standing for long periods, and wearing comfortable shoes may ease it.

Something you can do this week

Some parents find pelvic-floor education useful now; your midwife can talk you through what helps.

What comes next

Movements often feel strong and rhythmic in the weeks ahead.
