33 weeks pregnant

What to expect this week

What's happening in week 3 of your pregnancy

33 weeks pregnant

Week 33 and you are probably counting down the days!

At a glance

  • Your baby's bones are starting to harden
  • Swimming is a great way to relax and get some exercise
  • Try and get in little naps when you can

How big is my baby at 33 weeks?

Your baby is now around 3-4lbs in weight and around 44cm long. They might already have a head of hair, and will have perhaps shifted position and gone head down in your womb, with their little legs folded up to their chest. This position readies them to move further down into your pelvis in preparation for birth!

Your baby's bones are also continuing to harden at this stage too, except for those in their skull, which stay soft and pliable to enable baby's head to be born safely.

Facts to know about your baby in week 33

  • Your baby is now around 3-4lbs in weight and around 44cm long
  • When babies are born, parts of their skull may overlap to help them squeeze out - leaving the head temporarily cone-shaped after delivery
  • The bridge of the nose isn't there at birth it grows later, so babies have a small `button' nose"
  • Your baby will now weigh close to 5lbs and measure up at about 45cm long

You at 33 weeks pregnant

You are probably really feeling (and looking) very pregnant now, and might have adopted the pregnant lady waddle thanks to your growing baby's position!

You might be feeling pretty exhausted quite a lot of the time, and finding you get out of puff and worn out more quickly than usual. Trying to keep as active as possible is still really encouraged though, even when you are at this late stage. Swimming is brilliant for mums-to-be as it is both a great way to relax and get a bit of exercise all while being supported by the water and feeling weightless. 

You could also give yourself an energy boost with nutrient and iron rich snacks when you feel yourself flagging (much better for you than chocolate!) - and of course, get lots of rest and feet up time!

Facts to know about you  in week 33

  • Scrubbing floors on all fours and sitting backwards on a chair can help your baby's head engage
  • Your amniotic fluid levels are at their lowest so your baby's kicks can feel a bit sharp!
  • The placenta can weigh around 2lbs.

What to think about in week 33

You might be having real problems sleeping now, not only because of your mega bump, but also because of the weird dreams which can occur in late pregnancy! It can be infuriating not being able to nod off – or nodding off then waking lots in the night – but try not to stress over a lack of sleep too much. Instead, just try and make it up when you can (and don't feel guilty about it!).

An afternoon snooze on the sofa, or in the sunshine in the back garden will do you the power of good – and you really do need to make the most of every opportunity to put your feet up and rest now!

Packing your hospital bag is probably on your mind and we’re here to help make sure you have everything you need. Most UK hospitals also offer our free newborn portrait service, so do add a soft cuddly blanket which is a perfect setting for those first photos, and why not bring along a small soft toy for your little one to snuggle up to.
