Week 31 – your 3rd trimester

This might be hard to believe, but you are almost there! You're very unlikely to go beyond another 9 or 10 weeks. You could have your baby in just 6 weeks, and this would not be considered early.
What's happening in my body?

Your baby and bump are still growing. In a couple of weeks, you will both go through a final growth spurt. Your baby still has lots of fattening up to do before the big day arrives.

If this is your first baby, then your midwife or doctor will probably check the size of your uterus (womb). This can be estimated by measuring up your stomach, from the top of your pubic bone, to the top of your bump.

They will also gently feel your belly to work out which way up your baby is positioned. Some babies will be head down, ready for birth. You may have felt your baby move into place and seen your bump shift downwards.

If your baby is head up, there's still time for them to get into position. Some babies will not move down into the pelvis ("engage") until labour starts.

If your baby stays head up, in the "breech" position, that could affect the type of birth you are able to have. In some cases, if the baby is in an awkward position, or the placenta is blocking their way down, then your midwife or doctor might recommend a caesarean. You can talk to them about the risks and benefits before you make a decision.
Feeding: breast or bottle

Have you thought about how you would like to feed your baby?

Breastfeeding is great for your baby because:

breast milk contains antibodies that help your baby fight infections
your baby is less likely to get stomach bugs and develop breathing problems
it's available whenever your baby needs it

Find out more about breastfeeding.

However, not everyone is able to breastfeed. There may be health reasons why you can't, for example if you are taking medication that could go into your breast milk, or if you're recovering from surgery. You can still get your baby off to a great start feeding with formula and lots of cuddles. Get advice about bottle feeding on the NHS website.

Right now, your baby will be practising sucking, which is a vital skill for feeding.
Baby sling safety

Many parents use a sling or baby carrier instead of a pram to keep their baby close to them. If you decide to use a sling, make sure you know how to use it safely, as a small number of deaths from suffocation have been linked to slings.

The Royal Society for the Prevention of Accidents (RoSPA) advises the safest slings are the ones that hold your baby solidly against your body, in an upright position. Make sure you can see your baby, that their face is not restricted, and their airways are always clear.

The “T.I.C.K.S” rule to keep your baby safe when wearing a sling or carrier is:

T – Tight

I – In view at all times

C – Close enough to kiss

K – Keep chin off the chest

S – Supported back

Read more about sling safety and the “T.I.C.K.S” rule on the RoSPA website.
3rd trimester pregnancy symptoms (at 31 weeks)

Are you getting fake contractions? You may feel your bump tighten up for 20 to 30 seconds, then relax again (it should not hurt). These are known as Braxton Hicks contractions and often referred to as "practice contractions".

These are perfectly normal and harmless. However, if they're painful, or you start to get them at regular intervals, it could be a sign of early labour, so contact your midwife or doctor.

Your signs of pregnancy could also include:

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)
bloating and constipation (read about bloating on week 16's page)
leg cramps (week 20 explains how to deal with cramp)
feeling hot
dizziness
swollen hands and feet
urine infections
vaginal infections (see week 15 for vaginal health)
darkened skin on your face or brown patches – this is known as chloasma or the "mask of pregnancy"
greasier, spotty skin
thicker and shinier hair

You may also experience symptoms from earlier weeks, such as:

mood swings (week 8's page has information on mood swings)
morning sickness (read about dealing with morning sickness on week 6's page)
weird pregnancy cravings (read about pregnancy cravings on week 5's page)
a heightened sense of smell
sore or leaky breasts (read about breast pain on week 14's page)
a white milky pregnancy discharge from your vagina and light spotting (seek medical advice for any bleeding)

What does my baby look like?

Your baby, or foetus, is around 41.1cm long from head to heel, and weighs about 1.5kg. That's approximately the size and weight of a coconut.

Your baby is very active, moving around, sucking their fingers, and doing the odd somersault. Day by day, your baby is getting plumper and looking less wrinkled. The amount of amniotic fluid surrounding your baby is increasing because your baby is now able to pee.

Your baby will start to recognise voices outside the womb, so encourage your partner and any other children to talk to your bump, to help create a strong bond between them.

Action stations

For the first few months, you'll need a crib, carry cot or Moses basket. If you're borrowing a cot, then ideally you'll need a new mattress. It should fit snugly with no gaps and be clean and waterproof. Do not use pillows or duvets, as they can cause your baby to overheat or even suffocate. Instead, get a baby sleeping bag or layer up with light blankets.
