Week 20

What’s happening this week

Your baby…

  • your baby measures about 16cm (CRL)
  • is about the size of a game controller
  • weighs about 300 grams
  • hair and nail growth continue
  • following a regular schedule of sleeping turning, sucking and kicking and has settled upon a favourite position within the uterus (you may become aware of these wake/sleep cycles).

You…

  • your belly button may poke out as your uterus presses upwards
  • the placenta reaches its largest size relative to the fetus, covering one-half of the uterine lining
  • 400mls of fluid now present in the amniotic sac
  • for some women fetal movements can still not be felt – they won’t be far away.
