The first trimester

Week one to week 12

The first trimester is a period of major development for your foetus and of profound physical and emotional changes for you. You may realise that you are pregnant straight away, however many women will not realise they are pregnant until at least week four or five. This is one of the reasons why women are encouraged to plan for pregnancy.

During the first trimester of your pregnancy, your body is undergoing dramatic changes. Physically you may experience symptoms during the first trimester such as fatigue, nausea, frequency of urination and breast changes. Find out more about these symptoms, antenatal care, which foods to avoid and travelling precautions during the first trimester.

The second trimester

Week 13 to week 27

The second trimester is often considered to be the best period of pregnancy. You will probably find that many of the side effects of the first trimester have begun to disappear and you should begin to experience a general feeling of contentment and well-being. Also, you do not yet have the full weight of a maturing baby placing stress on your body.

You will notice a number of changes during the second trimester such as changes to your digestive system, your body shape and breathing, and you will feel your baby beginning to move. Now is a good time to prepare for baby. Find out more about the second trimester.

The third trimester

Week 28 to birth

In the third trimester you will probably be feeling a combination of excitement as the birth approaches, mixed with an increasing desire to hurry things along. As you are now carrying a large weight around, you will experience a number of symptoms related specifically to your increasing size. By now your uterus, which used to weigh about 50g, will be carrying your baby, the placenta and up to about a litre of amniotic fluid, so it is little wonder that you will be feeling a bit uncomfortable.

Find out about preparing for labour, preparing your home for the baby and the physical changes you're undergoing during the third trimester.
