At week 29 your baby's muscles and lungs keep maturing, and the kicks can be strong enough to take your breath away.

Your baby this week

Muscles and lungs
Both are maturing, ready for life outside.
Head
The head is growing to make room for the developing brain.
Strong kicks
Movements are powerful and easy to see from outside.

What you might notice

  • Constipation and heartburn, both often worse now.
  • Varicose veins in the legs. Moving often and putting your feet up help.
  • Tiredness returning as you carry more weight.
  • Feeling breathless doing ordinary things.

Call your midwife, doctor or maternity unit today if

  • Your face, hands or feet swell suddenly, or you have a bad headache or blurred vision
  • You have bleeding, fluid leaking, or regular tightenings or period-like cramps
  • Your baby's movements have slowed down or changed
  • You have strong itching, especially on your hands and feet

Any time of day or night. You will never be a nuisance for calling.
