Week 39 – your 3rd trimester

Pregnancy normally lasts around 40 weeks and most women will go into labour a week either side of their due date. That means any day now.
What's happening in my body?

You might be getting a lot more discharge in your pants than usual. This should be thin, white and not smell of very much. If you spot a slimy blob of mucus that's yellow or bloody, then that's called a "show". This sticky stuff used to plug up your cervix and when it comes out, it can be one of the first signs that your baby's on the way. However don't grab your hospital bag just yet, as you could still have days to wait.

You may be getting back pain as your baby moves down your pelvis and starts head butting your spine. You'll probably feel increased pressure at the bottom of your bump now.

You could also be getting sudden bursts of energy and urgently want to fold baby clothes or tidy drawers that you haven't opened for years. That's your nesting instinct kicking in.
9 signs you shouldn't ignore

If you get any of the following signs, then treat it as an emergency and call your midwife, doctor or NHS 111:

bleeding from your vagina
brown or pink discharge
severe itching, particularly at night
a terrible headache that won't go away
vision problems (blurring, light sensitivity, seeing spots or flashing lights)
pain just below the ribs
extreme swelling of the feet, ankles, hands and face
persistent stomach pains
a high temperature (above 37.5 degrees C) with no other flu or cold symptoms

7 things you might not expect when your baby's born

Babies don't usually come out wailing, like they do in the films. It could take a few seconds before they cry or splutter to clear their airways.

Your baby will be checked out within a minute of being born. You might not be aware of it, as you'll be meeting your baby at the same time. Your baby will be rated on the Apgar scale for their heart rate, breathing, muscle tone, responsiveness and skin colour. This will be rechecked at 5 minutes.

Your baby's hands and feet might be blue, as their circulation is still a work in progress. The rest of their skin will be dark red or purple, then turn a brighter red when they take their first breath. It can take weeks before their true skin colour is revealed. If your baby's rubbed vigorously with a towel, this doesn't mean that there's a problem, it's probably just to help the blood flow.

It can take a few minutes before your baby's breathing regularly. They tend to do lots of fast breaths, then lots of slow breaths. The gap between breaths can be as long as 5 seconds. They're just learning to breathe, so this is normal.

Boys can be born with large testicles – that's just temporary, caused by hormones and water retention. They will settle down and look more in proportion soon.

It's not always love at first sight. Give yourself time to bond with your baby and ask for help if you need it.

It can take 6 weeks for your womb to go back to the size it was. Breastfeeding can speed this process up as it makes your womb contract. Find out more about your body after the birth on the NHS website.

3rd trimester pregnancy symptoms (at 39 weeks)

You could be getting a lot of practice contractions, but if they start getting painful, then they could be the real deal. Read 5 signs that baby's on the way on week 37's page.

Phone your hospital or midwife when your contractions last for at least 60 seconds and come every 5 minutes – or call any time if you're worried that something is wrong, such as if your baby stops moving or if you're losing blood.

Your signs of pregnancy could also include:

painless contractions around your bump, known as Braxton Hicks contractions
sleeping problems (week 19 has information about feeling tired)
stretch marks (read about stretch marks on week 17's page)
swollen and bleeding gums (week 13 has information about gum health during pregnancy)
pains on the side of your baby bump, caused by your expanding womb ("round ligament pains")
piles (read about piles on week 22's page)
headaches
backache
indigestion and heartburn (week 25 talks about digestive problems)

leg cramps (week 20 explains how to deal with cramp)
feeling hot
dizziness

urine infections
vaginal infections (see week 15 for vaginal health)

What does my baby look like?

Your baby, or foetus, is around 50.7cm long from head to heel, and weighs about 3.3kg. That's approximately the length of 5 courgettes and the weight of a mini watermelon.

A few weeks ago, your baby's skin was almost transparent but now they're growing a tougher new layer that's looks more solid. This is better at protecting their internal organs and helping with temperature control.

The skin will be coated in a white, waxy substance called "vernix", which means varnish in Latin. This creamy layer helps to protect their skin and eases your baby down the birth canal. Your baby might be covered in it when they are born, or it could be mostly gone.

Action stations

Be on full alert in case your waters break, as this could happen at any time. Don't expect a tidal wave, as it could be just a trickle. If you think it's started, then call your midwife or doctor and ask for advice. You might have just wet yourself, but if your waters have broken, then your labour may need to be induced as your baby will be at a greater risk of infection.
