37 weeks pregnant - all you need to know

Your baby is considered ‘full term’ now. They’re about the length of a stalk of Swiss chard.

What does my baby look like at week 37?

During this final month, your baby will move further into the pelvis. Almost all babies are positioned head down, and most face their mother's back.. You can read more about the ideal position for labour and birth here.

When the head moves down into the pelvis, your midwife will describe it as ‘engaged’ - you might even notice your bump drops slightly.

Your pregnancy symptoms in week 37


Some women get piles during pregnancy. They are caused by the downward pressure from the bump. These small lumps are part of your blood vessels that have ‘popped out’. They can be inside or outside your anus can be uncomfortable and particularly sore when you do a poo.

Use a cool cloth to ease the discomfort - and talk to your midwife about ways to manage them.


Your womb pressing on your stomach can leave you bloated, burpy, sick or with a nasty heart burning sensation.

Other common pregnancy symptoms include headache, constipation and swollen feet.

Do you have an urge to clean?

Noticed a sudden burst of energy and the need to sort out everything in your house? You’re not alone - lots of mothers report this.

If you find that you are over-cleaning or find yourself needing to do some things over and over again, speak to your midwife about it, as it could be a mental health condition. 1 in 10 women have a mental health condition in pregnancy and it can come upon you even if you have never had one before.

What to do in week 37

If you find you are feeling very anxious about the birth and afterwards, talk to your midwife or doctor about it.

Getting help and support for your emotional wellbeing

‘Book a treat for yourself, like a massage, for after your baby’s arrival. Knowing that two months after my due date I’d be able to have some ‘me’ time again was a goal to work towards.’ Zoe, mum of one

Go to sleep on your side if you're not already doing so

When you reach your third trimester, the advice is to go to sleep on your side because research has shown that going to sleep on your back is linked to an increased risk of stillbirth. This advice includes daytime napping and night sleeping. Read more about safe sleep positions in pregnancy.

Expecting twins?

If you are expecting twins or more, you’ll probably be having your babies very soon - twins are born earlier than single babies.

The pregnancy length for multiples is:

  • Twins: 37 weeks
  • Triplets: 34 weeks
  • Quadruplets: 32 weeks.

If your babies are not born by then, most twin pregnancies are induced by 38 weeks because the health risks increase after that.

Practical plans for the birth

Still haven’t packed your hospital bag? Get to it! Your baby could arrive any day now.

If you have other children, make arrangements for someone to look after them when you go into labour.

This is also a good time to consider your support after the birth too. Who could you ask to help out every now and then?

Think about how you’ll get to the hospital or unit where you plan to give birth. If your birth partner will be driving you, it’s important to make sure there’s enough petrol in the car and that they are sure of the route and where to park.

Remember any change for the parking charges too!
