You at 18 weeks pregnant

You might be feeling baby’s movements now – like butterflies in your tummy. But it could still be a few weeks, so don’t worry.

Emotions in pregnancy
Pregnancy is a time when emotions can change. If you’ve had depression in the past or you’re feeling sad and not enjoying life the way you used to, tell your doctor or midwife.

For information, you can visit the PANDA (Post and Antenatal Depression Association) website or call PANDA on 1300 726 306. You can also call Beyond Blue on 1300 224 636. Many hospitals also have mental health workers who can give you support and counselling.  

You and your partner
You might:

  • feel more vulnerable and tired than usual and need extra support
  • need to talk about the pregnancy more than your partner does
  • not feel like sex as often as you used to.

If you have a partner, it’s a good idea to talk about the changes that your baby might bring to your lives.

Even if you feel like your relationship is strong, putting extra effort into communicating openly, working out your roles and sharing expectations is good practice for parenting and staying connected. This ‘relationship work’ can be everything from deciding on paid work arrangements to talking about who cooks dinner.

The second trimester is also a great time to be together as a couple and do some things that you’ll have less time for in the early months after baby is born. Sleeping in, watching a movie, going out for a meal and visiting friends and family are just some ideas.

Your baby when you’re 18 weeks pregnant

This is what baby is doing now:
  • Your baby measures about 14 cm from head to bottom, and weighs about 200 gm.
  • Your baby’s bowel is filling with meconium – this is the hard, black sticky stuff that will come out in your baby’s first poos.
  • Your baby is probably resting when you’re active – during the day – and playing at night, when you’re sleeping.
