Watch our video to see what your baby looks like this week
Your baby’s immune system is now fully ‘go’, and gratefully grabbing your own antibodies as they pass wombside – to beef up defences against the germs your baby is likely to meet in the outside world.
And here's a 3D scan of a 33 week baby...
So what's happening with your body this week?
Your weight gain's speeding up - and that's because your baby's ‘chubbing up'. You'll probably find you're putting on 0.5 kilos (1lb) a week now, working out at about 5 to 6 kilos (12 to 14lb) in total for this third trimester. (It's not all baby; some of it is extra ‘baby-support' stuff, like more blood and amniotic fluid or a bit of fat storage for breastfeeding prep.)
Your midwife should keep an eye on your weight gain (too much too rapidly can sometimes signal complications such as pre-eclampsia or gestational diabetes) and she'll certainly be checking your baby's weight with a special bump tape measure. Hardly state of the art but a surprisingly reliable bit of old tech.

Did you know? Your baby's now the length of... a Colin the Caterpillar cake

And is around the weight of... a 2-litre bottle of water
Your baby now weighs around 4lb 6oz (2kg)!

MFMers' tip of the week from our forum
“Breastfeeding? I'm going to give it a go again this time but won't beat myself up like last time if it doesn't work out. Don't worry what others think. At the end of the day, it's your baby, your body and happy mummy means happy baby” - emsypops

Is it safe... to use hair removal cream?
This preg joke is on us. Just as it starts to get really tricky to remove those pesky hairs, they grow faster than ever. Thanks hormones, we owe you one.
If you like to depilate using a cream, it is safe. Depilatory creams work by altering the hair protein, keratin, which breaks the hair. There's no harm to the baby or your baby's fine downy hair. But, the smell could be a stinker for you, because your nose is likely to be super sensitive.

And another super sensitivity (apart from a tendency to cry at anything and nothing – who knew Great British Bake Off was so sad?) is your skin. You may find you suddenly develop an allergic rash after using the cream. So, hair or spots – the choice is yours...
Our preg recipe for week 33 - Sticky chicken with mango couscous
Why mango is great for your growing baby
Sweet, sticky and moreish, the mango tastes so good, it can’t possibly be healthy, can it? You bet it can! Let’s pause and wipe the mango juice off our pregnant chins just long enough to point out the generous levels of iron, vitamin C, betacarotene, vitamin B6 and potassium we’re scoffing – and generously passing on to our babies. Mangoes are fibre-rich, too, which is good news for any third-trimester, erm, blockages.
Baby namer - what do you think of these space-themed names?
7 weeks to go. Decided on a name yet? If nothing has taken your fancy, what about these intergalactic names? They're out of this world!
Stella means star in Latin and is a celestial choice. Not only the brightest point in the night sky, a star is also a very famous or talented entertainer – so Stella may be destined for great things.
