What's happening in my body?
At your antenatal appointment, which is due around now, your midwife or doctor will measure the size of your bump with a tape measure and check your blood pressure.
They will also look for any protein in your urine that could indicate that you've got a dangerous condition called pre-eclampsia. This can happen in the 2nd half of pregnancy or after the baby is delivered.
If you're having a planned caesarean, otherwise known as an elective caesarean, then you'll probably be booked in when you're at least 39 weeks' pregnant. This is to give your baby's lungs the best chance of being fully developed.
You'll have a chat about what might happen if you go beyond 41 weeks. There could be risks for you or the baby, so you may be offered an induction. This is where labour can be brought on artificially by putting a tablet or gel in your vagina. Around 1 in 5 labours are started this way.
RSV vaccination
Have you had the RSV (respiratory syncytial virus) vaccine? It's usually offered at around week 28 but can be given later if needed, right up until you go into labour.
Having the vaccination can lower your baby's risk of a severe lung infection called bronchiolitis, which can make it difficult for your baby to breathe and feed. If you've not had it yet, speak to your midwife or a GP.
5 tips for a happy home birth
Around 1 in 50 women in England have their babies at home, supported by a midwife.
Here are some tips for a happy, healthy home birth:
- Be organised and have everything put aside for the big day, which should include something to wear in labour, a nursing bra, breast pads, maternity pads and new-baby essentials.
- Plan pain relief with your midwife. You may want a TENS machine, a birthing ball and a birthing pool. You can arrange for your midwife to bring Entonox (gas and air) and pethidine on the day.
- Put aside some towels and waterproof sheets – you'll need them to soak up the fluids.
- Think about the atmosphere you'd like to create – will you burn scented candles and play your favourite music?
- Have a bag packed just in case there are complications and you need to get to hospital in a hurry. Week 33 has advice on what to pack.
Flexibility is the key, whatever type of birth you choose. Ultimately your baby is the boss – and all everyone wants for you is a safe, peaceful delivery.
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 "Ticks" 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

What does my baby look like?
Your baby, or foetus, is around 49.8cm long from head to heel. That's approximately the length of a stick of rhubarb.
In the 2nd trimester, your baby was covered in a furry coat of soft, downy hair (lanugo). That's mostly gone now, although some babies are born with patches here and there.
Your baby is storing up some sticky green slime in their bowels (meconium). This is made up of everything they swallow in the womb, including bits of amniotic fluid and hair. It will normally come out after the birth as the first poo.
If the baby does a poo during labour, it can be a sign of distress and your baby will need close monitoring.
