You might have heard that it’s not a good idea to lie flat on your back. This is because your uterus can press on a big vein called the vena cava, which runs down the right side of your back.

If you’re uncomfortable, sit up slightly, lie on your side, and put a pillow under your stomach.

Staying active

Although you might be feeling slower and less energetic, physical activity is still important. It will help you prepare for and recover from birth.

Some women find swimming or aqua exercise is good, because it takes the weight off their legs and feet. Check with the instructor about suitable movements and swimming styles. You might also like to try pregnancy yoga or Pilates.

Before you start anything new, or if you have any concerns about staying active, check with your midwife or doctor.

Whooping cough immunisation

If you haven’t already had your immunisation against whooping cough, talk to your GP or midwife. In Australia this immunisation is free to all pregnant women in their third trimester.

Your baby

  • will put on lots of weight between now and about 38 weeks
  • has organs that are almost all functioning well
  • has started to produce red blood cells in the bone marrow
