Pregnancy first trimester

Even though you are in the very early stages of pregnancy, it is possible for you to start having pregnancy symptoms. One of the earliest signs you may spot is a prickling or tingling feeling in your breasts.

Some women get food cravings early in their pregnancy. You may notice that your food preferences have changed, and that favourite foods and drinks are suddenly unappetising.

It may seem an odd time but in fact it's a great idea to start an exercise routine now. Exercise helps you develop good muscle tone, strength and endurance.

Pregnancy symptoms continue or start this week. If you're like most women, you'll notice nausea (and not just in the morning), fatigue, the discomfort of sore breasts, and a need to urinate more often.

By the end of the week, your baby is about the size of a lentil. If you could see inside yourself, you'd find a large head and dark spots where the eyes and nostrils are beginning to form.

You may not look or even feel pregnant, but your uterus is expanding to accommodate your growing baby. Before pregnancy it was the size of a clenched fist; now it's as big as a grapefruit.

Your baby is now constantly moving and shifting, though you won't be able to feel anything for several weeks. The arms have grown and the hands are now flexed at the wrists and meet over the heart.

9 Weeks Pregnant
Pregnancy hormones are probably playing havoc with your body in all sorts of ways. Headaches and backache are both common when you are pregnant.

You're nearing the end of the first three months of pregnancy -- your first trimester -- and your uterus is about the size of a grapefruit, almost big enough to fill your pelvis (see our fetal development illustrations).

11 Weeks Pregnant
Your baby is now fully formed, from toothbuds to toenails and measures about the length of your thumb.

12 Weeks Pregnant
With luck your nausea will be on the wane and you'll soon be feeling more energetic. You're probably also feeling relieved because your risk of miscarriage has now dropped dramatically.

13 Weeks Pregnant
Birth is still months away, but your breasts may have already started making colostrum, the first milk that nourishes your baby immediately after birth, before the mature milk starts to flow.

Pregnancy second trimester

Hair is big news this week! Your baby is growing lots of it, not only on their head and brows but all over their body. This is covered in an ultrafine down, called lanugo, which usually disappears before birth.

15 Weeks Pregnant
One of the most exciting moments of pregnancy is feeling the baby move. Most women notice quickening, as it's called, between 16 and 20 weeks.
Image of a woman and her baby at 16 weeks of pregnancy.
16 Weeks Pregnant
It's perfectly healthy to put on weight in pregnancy. If you started out at a normal weight for your height (called your body mass index) you may have gained between 2kg and 4.5kg.
Image of a woman and her baby at 17 weeks of pregnancy.
17 Weeks Pregnant
First-time mums often start to feel their baby's movements around now. Many women report that the first sensations are fluttery or like butterflies in the stomach.
Image of a woman and her baby at 18 weeks of pregnancy.
18 Weeks Pregnant
Bigger, more comfortable clothes are a must now. Treat yourself to a new pair of shoes also in a bigger size, your feet will swell along with your body, and pick a low heel for extra stability as your bump grows.
Image of a woman and her baby at 19 weeks of pregnancy.
19 Weeks Pregnant
Congratulations! You're halfway there. This is a crucial time for the development of your baby's senses.
Image of a woman and her baby at 20 weeks of pregnancy.
20 weeks pregnant
Out of breath? You may start to feel a bit puffed out after going up just a short flight of stairs. Some breathlessness is normal and may become more pronounced over the rest of your pregnancy as your expanding uterus (womb) pushes up against your lungs.
Image of a woman and her baby at 21 weeks of pregnancy.
21 weeks pregnant
Your baby can now hear your conversations. If you talk, read or sing to your baby, expect them to hear you.
Image of a woman and her baby at 22 weeks of pregnancy.
22 Weeks Pregnant
You'll probably notice you're steadily gaining weight and that your appetite is increasing. Don't give yourself a hard time if you give in to an occasional yearning for ice cream.
Image of a woman and her baby at 23 weeks of pregnancy.
23 Weeks Pregnant
You may notice some bleeding when you brush your teeth. This is a common pregnancy complaint, along with nosebleeds.
Image of a woman and her baby at 24 weeks of pregnancy.
24 Weeks Pregnant
You may notice faint red streaks, or stretch marks on your tummy, hips, bottom and breasts. Rubbing on creams can make you feel more comfortable and help soothe any itching you may feel but it won't get rid of stretch marks or prevent them.
Image of a woman and her baby at 25 weeks of pregnancy.
25 Weeks Pregnant
You may feel the need to put your feet up a bit more often now. Even though tiredness may be making a comeback, try to stay active.
Image of a woman and her baby at 26 weeks of pregnancy.
26 Weeks Pregnant
Now that you probably have a noticeable bump you will get lots of comments on whether it's too big or too small. Sometimes both on the same day!
Image of a woman and her baby at 27 weeks of pregnancy.
27 Weeks Pregnant
Your baby can now open and close their eyes, sleeps and wakes at regular intervals, and may suck a finger or thumb.

Pregnancy third trimester

If your hair is more lustrous than usual, enjoy it while you can! During pregnancy, your hair becomes thicker, because hormones prevent normal hair loss.

40 Weeks Pregnant
Although it's a tight squeeze in there, your baby is still busily growing. Their hair and fingernails will be getting longer too.
Image of a woman and her baby at 39 weeks of pregnancy.
39 Weeks Pregnant
Don't worry if by the end of this week you're still waiting. Only about five per cent of babies are born on their expected due date. Most babies are born either earlier or later.
Image of a woman and her baby at 38 weeks of pregnancy.
38 Weeks Pregnant
Your baby is ready to greet the world. At this stage, they're still building a layer of fat to help them control their body temperature after they're born.
Image of a woman and her baby at 30 weeks of pregnancy.
30 Weeks Pregnant
Getting a good night's sleep can become more difficult again in the third trimester. As your bump grows, getting and staying comfortable is harder.
Image of a woman and her baby at 31 weeks of pregnancy.
31 Weeks Pregnant
Is your baby keeping you awake at night? Over the next few weeks, your baby's movements may start to feel more wriggly and squirmy, as they're growing fast.
Image of a woman and her baby at 29 weeks of pregnancy.
29 Weeks Pregnant
As your appetite increases to match your baby's third trimester growth spurt, it's tempting to fill up on cakes, chocolate and fast food snacks. Try to keep these to occasional treats rather than staple snacks.
Image of a woman and her baby at 28 weeks of pregnancy.
28 Weeks Pregnant
You're probably torn over how you feel. You may be thinking, "I've been pregnant forever", and "Help, I'm not ready for this."
Image of a woman and her baby at 33 weeks of pregnancy.
33 Weeks Pregnant
You may notice that your feet, hands, face and ankles have become a bit swollen. This water retention is known as oedema. It is often worse in warm weather and later in the day.
Image of a woman and her baby at 32 weeks of pregnancy.
32 Weeks Pregnant
You may be worrying if sex in the final months will harm your baby. Well, there's no need to worry. For most women, sex during pregnancy is fine right up until their waters break.
Image of a woman and her baby at 34 weeks of pregnancy.
34 Weeks Pregnant
If you've been worried about going into labour early, you'll be happy to know that the vast majority of babies born at 34 weeks onwards are perfectly healthy.
Image of a woman and her baby at 36 weeks of pregnancy.
36 Weeks Pregnant
Congratulations! By the end of this week, your pregnancy will have come full term. This means your baby can be born any day now.
Image of a woman and her baby at 37 weeks of pregnancy.
37 Weeks Pregnant
The next couple of weeks are a waiting game. However hard it is to be patient, try to enjoy this time before your baby arrives. Eat well and get plenty of rest.
Image of a woman and her baby at 41 weeks of pregnancy
41 Weeks Pregnant
It's hard not to be anxious when your due date comes and goes and you're still hugely pregnant (especially when well-meaning family and friends keep calling to check on your status!). But don't worry – you won't be pregnant forever.
