29 weeks pregnant - all you need to know

Your baby is about 33cm from head to bottom and about the size of a butternut squash.

What does my baby look like in week 29?

As well as being able to open their eyes and focus, they can turn towards light outside the womb.

Your baby is still developing more fat under their skin, which means they're less wrinkled and their skin is smoothing out.

Your pregnancy symptoms in week 29

Pregnancy heartburn

Your baby and womb have grown to the point that they are pushing into your stomach, which can give you heartburn, which is when the stomach acids that are normally used in the stomach to digest food are pushed upwards out of the stomach and into your throat.

Try to eat little and often, and avoid fatty and spicy foods, which are known to make heartburn worse 

A milky drink may also help. If this doesn’t work, your midwife or doctor will be able to prescribe you something, which is suitable in pregnancy.

Are you suffering from heartburn, indigestion or constipation?

Here’s our guide to 10 common pregnancy complaints (and how to avoid them).

Varicose veins?

You may be suffering from varicose veins. This is where veins - generally in the legs - become swollen and bumpy.

If they are a problem, put your feet up whenever you can and consider wearing support tights. If your legs are swollen and painful or if lumps appear talk to your midwife or doctor.

Belly button

Your belly button might start sticking out a bit now. It will go back in after your baby is born.

Stretch marks

You might have some stretch marks. They’re difficult to avoid, but they will fade after the birth with time. Read more about what causes stretchmarks and whether creams work.

What to do in week 29

Start going to sleep on your side

Research has shown that going to sleep on your back is linked to an increased rick of stillbirth so it is important to remember to go to sleep on your side in the third trimester of pregnancy. You can read more about the best sleep positions in the third trimester.

Maternity leave

Week 29 of your pregnancy is the earliest you can start your maternity leave. Many women prefer to work for longer, though, and save their maternity leave for after they have the baby.

Slow down but don’t give up

As your bump gets bigger, you may start to feel more easily out of breath - especially when you’re climbing stairs.

It’s OK to slow down and adjust your moving pace to a speed that your body can handle. But continue to be active as it is healthier than being sedentary (sitting down a lot).

Find out more about how active you should be during your pregnancy.

Pain relief in labour

Do you know much about pain relief in labour and birth? It’s worth reading up on the pros and cons of all your options, so you can go in to labour prepared.

Flying in late pregnancy

It’s not too late to travel in week 29, but different airlines have different policies so don’t forget to check before you book. Bring your pregnancy notes with you, stay hydrated on the plane and check that your travel insurance covers your pregnancy.

“We took our toddler abroad for the first time when I was about 30 weeks pregnant with no.2. It was lovely having quality time just the three of us before we became a family of four.”
