27 weeks pregnant - all you need to know

Your baby’s about the size of a cauliflower now.

What does my baby look like? 

You’re coming to the end of the second trimester now, and your family might find it easier to feel your baby’s movements.

If your baby was able to stretch out fully, they could be as much as 37cm long. They’re a tangle of limbs, taking up lots of the space in your womb.

Your baby’s heart rate has slowed down a little, to about 140 beats per minute - although this is still super-speedy compared to your own.

Their heartbeat can now be heard through a stethoscope and your partner might even be able to hear it if they put their ear to your bump - although it can be tricky to find the right spot.

Your pregnancy symptoms in week 27

Feeling constipated?

Progesterone, a key pregnancy hormone, slows down your bowels, which can leave you feeling bloated and constipated.

Try drinking lots of water and eating fibre-rich foods. As long as you feel well and comfortable, gentle exercise is also good for reducing constipation.

If these don’t work and it’s causing you a lot of discomfort, there are gentle medicines you can try. Talk to your midwife first about what is safe to take in pregnancy.

Suffering from cramps, constipation, heartburn, indigestion or headaches?

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

Your emotional wellbeing

Life goes on when you’re pregnant, and you might have to go through stressful events - such as the death or illness of someone in your family, a major renovation or house move, or a break-up with your baby's father.

Your pregnancy hormones can also make it harder to deal with stressful situations. If you feel overwhelmed, talk to your midwife or doctor about it - it might help relieve some of the anxiety and stress. You may also want to try our pregnancy and post-birth tool to help you think about how you are feeling.

What to do in week 27

Book a hospital visit

Have you thought much about where you’d like to give birth? If you decide to have your baby at your local hospital, now’s the time to enquire about visiting the labour ward.

You might find it helpful to arrange a trip so it isn’t completely unfamiliar when you go in to have your baby.

You might also want to start thinking more about the birth plan.

Don’t forget your pelvic floor!

You’re probably sick of hearing this - but, trust us, toning up your pelvic floor muscles is worth it.

It can be helpful to link your pelvic floor exercises to something you do often, such as waiting for the train or waiting for the kettle to boil. This will make it easy to remember to do them.
