Pregnancy week by week

How you and your baby are changing week by week

Track your pregnancy week-by-week

Whether you’re a first time mum-to-be or proud mother of three or more, our week by week guide provides helpful advice, information and topics to think about in each week.

In the first few weeks of pregnancy you may not even realise you’re expecting, but there’s a lot of changes going on inside your body. In week one your baby’s sex will already be decided and their brain will be starting to form, while by week six your baby’s heart is beating.

At the end of your first trimester (week 12) you will get a glimpse of your little one in your dating scan, with your next scan happening when you are around 20 weeks pregnant. Find out more about what to expect at your 20 week scan here.

At 27 weeks pregnant you enter your final trimester and are on the home strait. By 35 weeks it’s a good idea to have your hospital bag packed, and at 38 weeks your baby will be full formed and ready to be born. All that’s left to do now is play the waiting game for your new baby to arrive. Can’t wait? Try our fun tips for bringing on labour naturally.
