30 weeks pregnant: advice, symptoms and what to expect

by Deborah Cicurel |

Eek, you're 30 weeks pregnant, and your due date is rapidly approaching! At thirty weeks pregnant, you're in month seven of your pregnancy and your baby’s more proportional than ever, your dreams are getting weird and there are many other bodily changes taking place for both mum and baby.

Find out more about what else is happening to you and your baby in week 30 of your pregnancy.

How big is my baby at 30 weeks?

At 30 weeks pregnant, your baby’s the size of a cabbage, weighing in at three pounds and measuring nearly 16 inches long.

They'll be going through weight gain, at a rate of half a pound a week, for the next seven weeks.

1) Tiredness

That energy you may have enjoyed during your second trimester has sadly departed by now, and your growing baby and changing body may be leaving you exhausted.

Rope in friends, family and your partner for assistance with chores that leave you fatigued - it’s good to start practising asking for help now, as you’ll need plenty more when the baby arrives!

What’s my baby doing at 30 weeks pregnant?

By now your baby’s body parts will start to look more proportional. The only exception is their head, which will still be quite large compared to the rest of their body.

Their fingernails will be fully developed and will continue to grow in the womb, meaning that when your baby is born, they could be quite long and need cutting to prevent them from scratching themselves.

Your baby is currently surrounded by a pint and a half of amniotic fluid, but as they get bigger and take up more room in your uterus, that volume will shrink. As they grow, the space in your womb gets more cramped, so you may feel fewer hard kicks than you used to a few weeks ago.

Their brain is changing too, not just growing, but changing in appearance, too. Once smooth, the vital organ is now maturing and developing those grooves and indentations you’d normally recognise in a brain. These changes will allow more brain tissue to develop.

Thanks to your baby’s developing brain and new fat cells regulating their body temperature your baby’s lanugo (the soft hair covering their body) will start to disappear, too.

There’s another change, too: your baby’s bone marrow has taken over from the tissue groups and spleen in producing red blood cells, another important step towards independence once they are born.

What is my body doing?


It’s not the kind of thing you want to be overheard talking about on the bus to work, but during pregnancy, the amount of discharge produced can increase. It should still look and smell the same as before. If it changes and becomes thick, smelly, profuse or changes colour, see your doctor to check if you have thrush or an infection. It’s important you get this checked out as some infections can increase the risk of premature labour.

Prevention methods? Wear breathable cotton underwear and avoid strong soaps or feminine washes as they disrupt the natural pH and growth of healthy bacteria in the vagina.

There might be some more unpleasant pregnancy symptoms, too, especially the ones you thought you’d left behind in early pregnancy, such as needing to pee constantlytender breasts and heartburn.

What to do this week:

Although it may not be at the top of your list, keeping active while pregnant can help you to have a shorter labour and even experience fewer complications. It's recommended that pregnant women do 150 minutes of exercise throughout the week.  There are lots of different exercises you could try including pilatesaqua yogacycling and of course walking. Just be sure to talk to your midwife or doctor before trying something new.

If you haven't already, you should also start researching and even buying your baby's car seatpushchair and any other baby gear you will need in the first few weeks of your newborn's life. We recommend spending some time getting to know these products and fitting the car seat in your car so you can feel confident using them.

If this is your first baby, next week you should have another appointment with your midwife where they will measure your blood pressure, the size of your uterus and test your urine for protein. It's also worth pulling together any questions you might have ready for this appointment.
