You at 40 weeks pregnant
Congratulations, you’ve reached your due date!
If you haven’t gone into labour yet, don’t worry. Very few babies arrive on their due dates, and around half of all pregnancies go past 40 weeks. Even at 41-42 weeks of pregnancy, your baby is still likely to be going very well – although you might be feeling pretty tired and uncomfortable.
Your baby’s movements might feel a bit different, usually because there’s less space. If you’re at all worried about your baby’s movements – or anything else – call your health professional or the hospital.
Induction of labour
Labour starts naturally at 37-42 weeks for most women. But if you’re worried your baby is overdue, you might like to talk to your midwife or doctor about how to get labour going, when induction of labour might be recommended, and what it involves.
If you haven’t had your baby by 41 weeks, you’ll have more frequent checks to make sure your baby is healthy. Your doctor, obstetrician or midwife will talk about your options at this stage, including induction of labour.
It’s important for you to feel that you have all the information you need to make decisions that concern you and your baby’s health.
It’s OK to ask:
- why the doctors and midwives think you need an induction
- how an induction will affect you and your baby – the risks and benefits
- what could happen if your baby isn’t induced and you wait for labour to start naturally.
Getting to the hospital or birth centre
You’ll need to get yourself to the hospital or birth centre to have your baby, unless you’ve planned a homebirth. It’s a good idea to plan:
- how you’re going to get there – for example, by car or taxi
- your route
- driving and parking arrangements – where you’ll park, cost of parking, and whether there’s enough petrol in the car
- which entrance to go to (especially at night, because it might be different from the daytime entrance)
- who’ll look after your other children, if you have any.
Your baby when you’re 40 weeks pregnant
