28 weeks pregnant - all you need to know

Your baby weighs about 1kg now and is roughly the size of an aubergine.

What does my baby look like in week 28? 

Your baby weighs about 1kg now and is roughly the size of an aubergine. They’re starting to take up more space in your womb and, as the weeks go by, you may start to feel a bit more uncomfortable and tired.

Your baby will be having periods of sleep and periods of activity, which you’ll probably be aware of because of their movements. You may have noticed that these movements are settling into a regular pattern.

Take note of the pattern as it will help you notice if your baby’s movements slow down. If this happens, it should be checked immediately.

Find out what to do if you notice a change in your baby's movements.

Your pregnancy symptoms in week 28

Are you feeling dizzy? Suffering from indigestion, cramps or headaches?

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

Funny feeling in your legs?

Do you get an uncontrollable urge to move your legs? Or perhaps a crawling, tingling sensation? This could be restless leg syndrome. It’s quite common in pregnancy - and usually strikes when you’re resting or in bed.

It will go away once your baby is born. For now, take a look at the NHS tips for easing symptoms.

Feeling uncomfortable

Use pillows as best you can to get comfortable. Try one supporting your bump, another for your back and then one between your legs.

Pillows will also help you go to sleep on your side, which is the safest sleeping position for baby in late pregnancy. Another trick for helping with this that women have told us about is tying their hair in a low bun, which makes back sleeping too uncomfortable for any length of time.

Finding it difficult to sleep?

Here are some tips to help you drift off.

What to do in week 28

Next midwife appointment

You may have a routine antenatal appointment at 28 weeks. You’ll be offered a blood test to screen for anaemia and any antibodies in the blood. You may be prescribed iron tablets if your iron levels are low.

Swim time

As well as being good for your circulation, swimming in pregnancy improves your muscle tone and increases your endurance (great for preparing for labour). It may also give you more energy and help you sleep better.

As your bump grows, the feeling of weightlessness in the water can be lovely and relaxing.

Birth plan

If you haven’t written your birth plan yet, you may want to start thinking about doing it.

Think about the different kinds of pain relief and which, if any, you may like to consider when you’re in labour.

Did you know that depending on where you live and your health, you could decide to give birth in hospital, in a midwife-led birth centre or at home? Read more about where you can give birth.

We also have a pregnancy and post-birth wellbeing plan, which is similar to a birth plan for your mental health. It can help you think ahead to make sure that you are supported after the birth. You can complete the wellbeing tool at any point during your pregnancy.
