Preconception is generally used to describe the time leading up to conception (typically 3-6 months prior to conception).
Preconception health is a woman’s health before she becomes pregnant.
Preconception health is critically important for a child’s developmental process because poor maternal health and diet before and in the early stages of pregnancy can lead to impaired fetal and infant growth, poor birth outcomes and long-term effects on cardiovascular and metabolic disease.
Ovulation and its role in pregnancy is best understood within the context of your menstrual cycle.
The average menstrual cycle lasts for 28 days where the first day of your cycle is the first day of your period.
Halfway through your menstrual cycle (typically between day 13 and 15), your ovaries release an egg, which then travels along your fallopian tube to your uterus.
This is known as ovulation.
Your ovaries also release the hormone oestrogen, which causes the lining of your uterus to thicken in preparation to receive a fertilised egg.
An egg lives for about 12 to 24 hours after it’s released. A sperm must fertilise the egg within this time in order for you to get pregnant. Sperm can live for up to 7 days inside your body.
If an egg is fertilised as it makes its passage along the fallopian tube, it then embeds itself in the lining of your uterus. This is where your embryo will grow to become a baby.
If an egg is not fertilised it breaks down. Your oestrogen levels begin to drop, causing the lining of your uterus to break down too. These then leave your body as you menstruate.As ovulation approaches you may notice some physical changes. These include:
Preconception care looks to improve the health of a woman and her partner before trying for a baby. This can be done with a Healthcare Professional to help understand current health status and consider strategies for improving overall health, fitness and lifestyle.
Preconception care is important because being as healthy as possible in the months before trying to have a baby has been shown to help the chances of falling pregnant. Plus, being healthy before falling pregnant gives your baby a better chance of good health throughout their life.
Currently there is no known safe level of alcohol, therefore, the safest option for women planning a pregnancy is to avoid alcohol.
This is because alcohol can affect fertility in both women and men. Heavy drinking can affect a woman’s menstrual cycle and ovulation and in men it can reduce the amount of testosterone in the blood.
A preconception plan allows you and your partner to plan ways to improve your health before conceiving. According to the Royal Australian College of GPs, a preconception care plan can involve a range of strategies including:
A preconception visit with a Healthcare Professional is recommended 3 to 6 months before you are hoping to become pregnant so that they can help you come up with strategies to help improve your chances of conceiving, plus improving the health outcomes of you and your baby.
It is a good idea for partners to attend a preconception appointment with a Healthcare Professional. This will enable them to talk through any family history of medical conditions at the appointment. Ways to support your fertility through diet and lifestyle changes (if any are needed) can also be discussed and requires the input and commitment of both parents-to-be.
Your body will go through some big changes over the next few months.
A normal full-term pregnancy is 40 weeks and divided into three trimesters:
Here’s everything you’ll want to know to help prepare you for the physical and emotional changes ahead.
The early days of pregnancy can be a very exciting time, but most of the time during Weeks 1-3 you do not even know you are pregnant yet! This doesn’t mean that there isn’t a lot happening inside your body.
Your pregnancy technically starts on the first day of your last period. If you have a typical 28-day menstrual cycle, your ovary will release an egg around Day 14. This egg will travel down the fallopian tube and come together with a sperm within 24-48 hours after ovulation. If the eggs fertilizes, things are about to get busy!
By three weeks, there is a lot going on in the uterus – even if you are not able to tell yet. The fertilized egg will continue to travel down the fallopian tube towards the uterus and will eventually embed itself in the lining of the uterus. Here it will continue to divide and grow.
During this time, it is common that you will not feel any symptoms at all – it is still very early. You will be able to confirm that you are pregnant on the first day after your missed period with a home pregnancy test or a blood test from your doctor.
At this stage your baby is now called an embryo and is already growing rapidly. The placenta is formed and will nourish your baby for the remainder of your pregnancy by passing nutrients to them through the umbilical cord.
Your baby’s development
Your body
By the fifth week of pregnancy, your baby is now an embryo. Your baby is as big as an apple seed, approximately 4mm in length and weighing less than 1g.
Their head is growing in size due to the rapid development of their brain and the neural tube closes around week four of their development. Meanwhile, the brain and other major organs continue to grow.
Your baby’s heart is already beating and pumping blood around their tiny body. Their arm and leg buds are starting to develop.
As your uterus adapts to your growing baby you may experience light cramping. Other symptoms are likely to be very subtle at this early stage, but may include tiredness, tender breasts, nausea and headaches.
Your baby has doubled in size over the last week and is now about 8mm long.
Their heart has formed distinct right and left chambers and beats somewhere between 150-160 times each minute, circulating blood around their developing body.
Your baby’s cells are highly responsive to the nutrition they receive at this important time of development. Recent science shows that their lifelong health is only partly determined by genetics and that external factors have a huge part to play.
Your progesterone levels are rising and you may start to experience morning sickness.
You may be feeling tired at the moment and it is no wonder with all that’s going on inside you. Your baby is growing rapidly. Baby’s lungs, liver and pancreas are all being formed and the eyes, inner ears, arm and leg buds are growing this week.

Your body
This week, your baby is starting to look more like a baby! Their face is beginning to take shape and their mouth and nostrils are starting to develop. The heart has divided into chambers and is beating about 150 beats per minute – about twice the rate of an adult’s!
Your baby’s development
Your body
Your baby is now moving freely in the amniotic sac. Their arms and legs have lengthened, fingers and toes are forming and brain waves can now be measured! Their head appears much larger than the rest of their body as the brain is growing very rapidly.
Your baby’s development
Your body
Your baby now has their own unique fingerprints! Their neck is beginning to take shape, their body muscles are almost developed, the jaws are in place and nipples and hair follicles begin to grow. While it is still too small for you to feel, baby is moving, wriggling and shifting.
Your baby’s development
Your body
Your baby can now swallow and stick out their tongue! Their taste buds are starting to develop and they may soon be able to taste different flavours from the amniotic fluid. Twenty little tooth buds are now forming – the beginning of your baby’s complete set of milk teeth.

Your baby’s kidneys are now producing urine and they are practicing making breathing movements even though they are getting the oxygen they need from the placenta. Their head is about a third the size of their body. Their first hair is now appearing on their head and eyebrow hair is developing.
Your baby’s development
Your body
Congratulations, you have reached your 2nd trimester! This trimester is often the stage of pregnancy that mums-to-be enjoy the most. The first three months were a period of rapid development but the next three will be a period of rapid growth! Your baby will quadruple in weight during the 4th month.
Your baby’s development
Your body
Your baby is now able to move its arms and even make a fist! Their legs have grown longer than their arms and their body is now longer than their head. Ears are nearly in place and the three small bones in the middle ear have begun to harden.
Your baby’s development
Your body
By now your baby has learned to breathe and is inhaling and exhaling small amounts of amniotic fluid. This will help their lungs develop and grow. Facial muscles are more developed so they may have different expressions like squinting or frowning. They are becoming more active and can kick or even somersault!
Your baby’s development
Your body
This week your baby’s fat stores are beginning to develop under their skin. The fat will provide energy and help to keep your baby warm after birth. Their retina has become more sensitive to light and their eyes are looking forward now but they are still firmly closed.
Your baby’s development
Your body
Your baby will begin to hear this week! They may be able to hear your heart beating, tummy rumbling or blood moving through the umbilical cord. They are now going through the motions of crying as their lungs are forming and vocal chords are formed, but without any air they are not making any sound… yet!
Your baby’s development
Your body
Your baby’s leg muscles are strengthening so soon you may be able to feel slight kicks. If you are having a boy, the genitals are now distinct and may be able to be seen on an ultrasound. If your baby is a girl, their uterus has started to develop.
Your baby’s development
Your body
You are now officially half-way through your pregnancy, congratulations! Your baby can now hear voices, music and sound from the outside world. Your voice will become familiar to them and soothe them after birth so make sure to have a little chat with your bump each day!
Your baby’s development
Your body
Up until now your baby’s liver and spleen have been producing blood cells but this job will now be taken over by the bone marrow. Your baby’s small intestine will now start to absorb small amounts of sugar from swallowed amniotic fluid.
Your baby’s development
Your body
Your baby now has their own regular sleeping and waking routine. Your movements may wake baby when they are sleeping, in the same way that their movements or kicks may keep you up at night! Their eyebrows and eyelids are fully developed and fingernails cover the fingertips.
Your baby’s development
Your body
Your baby is now turning from side to side or head over heels! Their inner ear is now fully developed which gives them a sense of balance so they may be able to tell if they are upside down or the right way up.
Your baby’s development
Your body
The lungs are developing further and baby practices breathing by inhaling amniotic fluid into their lungs. Baby is still covered in fine downy hair and a waxy substance to protect the skin. Taste buds have formed and if you drink or eat something strange or bitter baby may taste it!
Your baby’s development
Your body
Baby is getting more and more curious and explores their surroundings by touching the cord and feeling their face and hands. Their hands are now much more developed and they can make a fist or clasp as well as getting more familiar with their surroundings.
Your baby’s development
Your body
Your baby’s brain is now growing rapidly. The part of their brain which registers conscious thought is gearing up – soon they’ll be able to store memories from their time spent inside the womb, ready to be recalled after they’re born.
Your baby’s development
Your body
Your baby is now around 37cm long and weighs almost 900g.
Facial features are fully formed and they look similar to how they will look at birth. Your baby’s lungs, liver, and immune system can function but are still developing.
During the third trimester of pregnancy, your placenta will start to boost your baby’s immune system by providing antibodies, which will eventually be needed to fight infection.
As you approach your final trimester, aches and pains are common as your body adjusts to accommodate your growing baby.
By 33 weeks, your baby will weigh around 1.85kg and measure about 44cm in length.
Your baby can listen, feel and even see. Your baby’s eyes can detect light, while their pupils constrict and dilate in response.
As you and your baby grow in size, you’ll need more energy. However many pregnant women experience acidity, heartburn and indigestion. This happens because of hormonal and physical changes. In fact, by now your stomach has got smaller, because your baby is taking up more room.
Your baby could be due any time now. By now, your baby is around 3.4kg in weight and measures around 51cm from head to toe.
During this time, varicose veins, if you have them, might get more pronounced. This is because the hormone progesterone relaxes the blood vessels. There’s also more weight on your legs and more blood circulating in your body.
The early signs of pregnancy include a missed period (although this symptom can be misleading if you have an irregular menstrual cycle). Changes in hormones can create a variety of symptoms. Which symptoms and when these occur can vary and may include tender and swollen breasts, nausea with or without vomiting (often referred to as morning sickness, which can strike at any time of the day or night!), increased urination, and fatigue.
Missing a period is generally the first sign of pregnancy.
If you think you’re pregnant, see a GP straight away to start your pregnancy care. This step is critical to ensure that you:
Pregnancy tests check urine or blood for the hormone called human chorionic gonadotropin (hCG). At around 4-5 weeks hCG are high enough for home pregnancy tests to detect a change.
Home pregnancy tests are fairly accurate; however, they do require the instructions to be followed correctly. Most home pregnancy tests can be taken 2-3 days after your period was due.
For a more accurate result, consult with a Healthcare Professional.
A Healthcare Professional is the best person to calculate your pregnancy date.
To estimate your due date yourself, most pregnancies last around 40 weeks (or 38 weeks from conception), so typically your due date is to count 40 weeks, or 280 days from the first day of your last menstrual period.
Braxton Hicks contractions are quick, usually painless contractions – a tightening of your uterus – that usually occur in the late second and third trimester. They help to prepare the uterus for labour, like practice contractions.
Braxton Hicks contractions usually last for anywhere between 30 seconds to 2 minutes.
For most women, morning sickness begins around the fourth week of pregnancy and disappears by the 12th to 14th week. However, one in five women endure morning sickness into their second trimester, and an unfortunate few experience nausea and vomiting for their whole pregnancy.
How much weight you should gain while pregnant will depend on your pre-pregnancy weight.
The following table should be used as a guide: as always, consult with a physician, dietitian or midwife to get specific health advice.
| Pre-pregnancy BMI | Recommended weight gain over the whole pregnancy | Recommended weight gain per month in the 2nd and 3rd trimester |
| < 18.5 | 12.5kg to 18kg | 2kg to 2.6kg |
| 18-5 to 24.918.5 to 22.9 if Asian | 11.5kg to 16kg | 1.5kg to 2.3kg |
| 25 to 29.923 to 27.5 if Asian | 7kg to 11.5kg | 1kg to 1.5kg |
| > 30Or over 27.5 if Asian | 5kg to 9kg | 0.8kg to 1.2kg |
Pregnancy cravings can strike at any time from the moment your body begins to release pregnancy hormones. In fact, new cravings or food aversions are often amongst the first, most noticeable signs of pregnancy.
The strength of your cravings may fluctuate throughout your pregnancy and can change from one month to the next.
Pregnancy hormones can cause emotional changes and some ups and downs are normal as you adjust to pregnancy.
However, some emotional changes can be more serious. These changes include feeling sad and not enjoying life the way you used to. If these changes last longer than two weeks and get in the way of daily life, it could be anxiety or antenatal depression.
There might be times when you need extra help and support to cope with some of the changes happening during your pregnancy.You may find it helpful to speak to a midwife, physician or psychologist if you’re:

When it comes to nutrition, parents want to make sure their children are getting all the vitamins and minerals they need to support growing brains and bodies. Both you and your growing baby need extra nutrients.
According to the World Health Organisation, proper infant nutrition is fundamental to a child’s continued health. Breastfeeding has been shown to be of critical importance to a child’s development, including increased IQ, school performance and higher income in adult life.
As per the Australian Infant Feeding Guidelines:
A nutrient-rich diet is important for healthy development in infants.
Breastmilk or formula has all the nutrients that babies need until they are around 6 months old. In Australia, it is recommended that you exclusively feed your baby, with no other milks, food or drinks, until about 6 months. In fact, your breast milk is perfect for your baby, even if born prematurely because your breast milk will adapt to meet your baby’s needs and protect against a range of illnesses.
From 6 months and onwards, infants require additional nutrients sourced from vegetables, dairy products, meat (or meat alternatives), grains, and fruit. These nutrients include fibre, vitamins and minerals.
The essential nutrients during breastfeeding are:
Protein
Folate
Iodine
Zinc
Vitamin A/Beta-carotene
Vitamin B6
Fats – or fatty acids – come in many forms: saturated, monounsaturated, polyunsaturated, trans fats.
Omega-3 and omega-6 are both polyunsaturated fats that we need in our diet as our bodies do not produce them. Omega-9 fats are nonessential fats that our bodies can produce.
Omega-3 fatty acids can help reduce the risk factors of developing heart disease. This type of fatty acid also plays an important role in the development of your baby’s brain, nervous system and eyes, and contributes to normal cognitive development, which enables your baby to think and learn.
As per the RACGP guidelines, if you are pregnant with one baby, you may take omega-3 supplements each day starting from around 12 weeks of pregnancy. You will need to take at least 500mg of DHA per day (not exceeding 100mg of DHA plus EPA per day). However, not all omega-3 supplements are the same so you should look for omega-3s called DHA and EPA.
If you are vegetarian, you may take omega-3s extracted from algal oil rather than fish oil.
Vitamin D is a hormone that controls calcium levels in the blood. It is needed for strong bones, muscles and overall health. 90% of vitamin D is obtained through sunlight on the skin with 10% attributed to dietary nutrients.
In Australia, it has been found that many pregnant women are deficient in vitamin D. Generally levels lower than 50nmol/L is considered as suboptimal.
In pregnancy, if you have a low level of vitamin D your baby will also have a low level when born. In babies, vitamin D deficiency can be associated with problems such as low birth weight, rickets, delayed motor development, muscle weakness, and fractures.
Because breast milk does not contain much vitamin D, guidance in Australia suggests consideration of a daily dose of 400 IU for pregnant women at higher risk.
Iron is needed to produce red blood cells. Your body makes more blood when you are pregnant because both you and your baby are growing. This means you need more iron when you are pregnant.
Pregnant women need 27mg iron each day but should not eat more than 45mg iron each day.Iron supplements should only be taken when a blood test has confirmed that your levels are low. It is best that you discuss what type of iron tablet is best for you with your doctor, midwife, or dietitian.
Water keeps our complex bodies working properly, helping to absorb nutrients and flush out toxins. During pregnancy, the increased demands on your body mean you need more water than normal.
Aim for 9 glasses of fluid per day. Water or reduced fat milk are the best choices. If the weather is hot, you have vomited or if you are constipated you may need more than this.
Suitable drinks for pregnancy include water, whether straight from the tap (if safe in your area), or bottled (either carbonated or still), milk and fruit juices. Juice can be high in sugar, but providing it is pure fruit, one 125mL glass can also count as part of your daily fruit and vegetable intake. Soup also counts and can provide a good serving of beneficial nutrients too.
Try to avoid drinks that are fizzy or high in sugar content. With little nutritional value, it’s best to avoid them or try a healthier alternative. You should also limit your intake of caffeinated varieties of tea and coffee. Caffeine can act as a diuretic, increasing your need to urinate. For pregnant women it is safe to consume up to 200mg per day of caffeine without effect on your unborn baby.
If you’re having trouble keeping fluids down due to morning sickness or a stomach upset, try to take small sips regularly rather than large gulps. Even small amounts add up and can lower your risk of becoming dehydrated; start by taking small sips and gradually increase the amount if you can.
It’s important if you are drinking herbal teas, to check for a warning label saying “not recommended for pregnant women” or discuss this with your Healthcare Professional.
While breastfeeding, your fluid intake increases even more to keep your own body hydrated and to provide the water required to produce a good supply of milk.
Carbohydrate foods provide essential fuel for both you and your baby during pregnancy. They are broken down into simple sugars like glucose. The brain requires glucose as the main source of energy. Glucose easily moves through the placenta and is required for the development, growth and metabolism of maternal and foetal tissues.
As such, carbohydrates should not be avoided during pregnancy. However, low-quality carbohydrates found in processed foods such as cakes, chocolate, biscuits should be minimised. Instead, high-quality carbohydrates found in wholegrain bread, rolled oats, yoghurt, starchy vegetables, beans and legumes should be consumed.
For pregnant women, dietary fibre is an essential part of a balanced diet.
The recommended daily intake of dietary fibre for women of childbearing age is 28g daily. Foods such as oat bran, whole wheat bread, whole grain cereals, legumes, nuts seeds, bananas, carrots and celery contain fibre.
After a review of scientific studies, there is no clear evidence to suggest a link between a mother eating peanuts and her child developing a peanut allergy. Unless you have a peanut allergy or a Healthcare Professional specifically advises you against them, peanuts and foods containing them are now considered safe to eat in pregnancy and while breastfeeding.
It is suggested that pregnant women eat 2–3 serves of fish every week for the good health of themselves and their developing baby. This is because fish is an important part of a healthy diet.
Some of the health benefits of fish include:
When fish is consumed as part of a normal diet, mercury from most fish sold in Australia is not a health risk.
However, pregnant women or women intending to become pregnant within the next six months should be careful about which fish they eat.
In excessive amounts, mercury can build up in the blood of the mother and be harmful to an unborn baby. The unborn baby is most sensitive to the effects of mercury, particularly during the third and fourth months of gestation.
In particular, unborn babies are at increased risk from mercury. The mercury in fish can lead to raised mercury levels in the mother. This mercury can be passed on through the placenta to her developing baby.
The Australian guidelines for safe levels of mercury in the diet recommend that pregnant women should:
Women should not be worried if they’ve had the odd meal of fish with high levels of mercury. It is only a potential problem when that type of fish is eaten regularly, which causes a build-up of mercury in the mother’s blood.
Methylmercury from fish consumed during pregnancy seems to only pose a health threat to the baby while it is in the womb. Upon birth, the levels of mercury in the mother’s milk are not high enough to pose a risk to the infant.
Pregnant women should aim to consume 5 serves of vegetables and legumes per day (source: eatforhealth.gov.au).
For women who are breastfeeding, the Australian Dietary Guidelines recommends women 18 years or under to eat 5½ serves of vegetables and for women 19-50 years, 7½ serves of vegetables per day.
Pregnant women should aim to consume 2 serves of fruit per day (source: eatforhealth.gov.au).While breastfeeding, the advice is to have 2 serves of fruit per day where a standard serve of fruit is about 150g or:
During pregnancy you’re advised to avoid certain foods which could be associated with an increased risk of food poisoning. As well as being unpleasant for you, food poisoning can also make your baby very unwell and may increase the risk of premature delivery, stillbirth, miscarriages and infections.
Folic acid (also known as folate) is a B-group vitamin and is an essential pregnancy vitamin. It plays a significant role in the formation of your baby’s neural tube. This is formed in the first month of pregnancy and eventually becomes your baby’s spinal cord and brain. Together, these will form your baby’s central nervous system and the control centre for your baby’s future growth, development, and normal functioning later in life.
An adequate intake of folic acid has been shown to reduce the risk of neural tube defects (NTDs) including spina bifida.
Although folate is present in many foods, it is difficult to get sufficient levels from your diet.
If you’re planning to have a baby, experts recommended that you take a supplement containing 400 mcg folic acid per day for 12 weeks before you conceive. This allows it to build up in your body to a level against help reduce the risk of neural tube defects, such as spina bifida. This requirement increases during pregnancy to 600 mcg per day until the end of the first trimester.
You should ask your Healthcare Professional for advice about your individual needs.
Calcium is essential whether you’re pregnant or not, but if you’re pregnant it’s particularly vital because it helps your baby build strong bones and teeth and plays an important role in the healthy functioning of the circulatory, muscular and nervous systems.
If you don’t get enough calcium during pregnancy, especially in the third trimester, your baby will draw it from your bones, which may impair your health and increase your risk for osteoporosis later in life.
During your pregnancy, the recommended daily intake (RDI) is the same as it is prior to pregnancy: 1000mg a day for women aged 19 to 50 years and 1300mg a day for adolescents or those aged over 51.
Most women in Australia do not get nearly enough of this important mineral. You should aim for 2-3 servings of dairy products or calcium-rich foods a day.
Pregnant adolescents (under the age of 18) should aim for 3-4 servings of dairy products a day.
