Planning for your pregnancy

Planning for your pregnancy

Planning to have a baby? There are some important things you can do to help that happen, and to give your baby the best start in life.

Both men and women’s fertility can be affected by drinking alcohol. If you are trying to get pregnant, both partners stopping drinking can be good support for each other and improve your chances of conceiving and having a healthy baby. Fertility New Zealand has some good information about fertility and alcohol 

There is no safe level of alcohol during pregnancy, so women are advised not to drink any alcohol at all if they think they might be pregnant, are pregnant, or are trying to get pregnant. 

If you have any concerns about your alcohol drinking, or want help to stop drinking, you can talk to your GP or contact the Alcohol Drug Helpline on 0800 787 797 or free text 8681 and they will text you back for a free confidential conversation. The helpline is staffed 24/7, is anonymous, and gets you through to a qualified alcohol counsellor or social worker. You can also go to their website for more information about their service, and to find local services to contact.

You can also find more information at, including a handy set of frequently asked questions about alcohol and pregnancy.

Alcohol can be a very hard thing to give up. Making the first step to ask for some help can really make a difference for you and your whānau/family.

Folate is a naturally-occurring vitamin, part of the B group vitamins. It is found in leafy vegetables, citrus fruits, wholemeal bread, yeast, liver and legumes. We all need folate in our diet, to allow cells to reproduce and grow. It is recommended that NZ adults consume about 400 micrograms a day, but in pregnancy that requirement goes up substantially.

Having enough folate reduces the chance of having a baby with a neural tube defect. Neural tube defects (NTDs) are a major group of birth defects where the brain, spinal cord, or the covering of these organs has not developed properly. Spina bifida and anencephaly are the most common types of NTDs.

Folic acid is the tablet form of folate, and taking a supplement of folic acid greatly reduced the chance of having a baby with a NTD.

Take a folic acid tablet (0.8 milligram [mg]) every day for four weeks (one month) before you might become pregnant, through to 12 weeks after becoming pregnant. You can buy these tablets at a pharmacy, or get them on prescription from your GP.

For more information visit the Ministry of Health website or read this leaflet about Folic Acid.

Stopping smoking before you get pregnant is one of the best things you can do for your health and for your baby. Smoking during pregnancy is one of the main causes of complications in pregnancy, linked to miscarriage and stillbirth and an increased chance of going in to labour too early. 

If you are trying to conceive it is important for you and your partner to stop smoking, as this can affect fertility. Both partners stopping smoking can be a good support for each other. Quitting smoking is easier when you’re not alone.

Hāpainga Stop Smoking Service and their stop smoking support person will give you free help and advice. Call this service free on 0800 427 246. Priority access is given to all people who are pregnant.

You can also contact the national Quitline on 0800 778 778 for support, or speak to your GP.

Weight is a very sensitive subject for many people. However, if you are planning to get pregnant it’s a good idea to establish healthy eating patterns and try to reach a healthy weight before you are pregnant. Women who are underweight or overweight can have a higher chance of problems in pregnancy.

What is BMI?

For most women, healthy weight is calculated using a BMI measurement. Your body mass index (BMI) is a comparison of your weight to your height. This is your weight in kilograms divided by your height in metres squared. You can ask your health practitioner to help you with this, especially if you do not have accurate scales at home.

New Zealand Health Navigator has an online tool that can help you calculate your pre-pregnancy BMI.

If you are concerned about your weight, please contact your midwife or GP for the best advice.

While you are thinking about starting a family it is very important to keep taking your medicines to manage your condition (particularly if you have epilepsy) and continue using contraception until you have talked to your doctor.

  • Stopping your medication without talking to your doctor can cause serious risk of harm to yourself and your baby if you are pregnant.
  • If you get pregnant before having a plan in place for your medication you could cause problems for your baby. Some of the problems that can happen to your baby as a result of the medication can happen in the very early weeks of your pregnancy.

Talk to your doctor as soon as possible, ideally at least 6-12 months before you want to start trying to get pregnant. This is because it takes time to safely change your medicines.

This doctor’s appointment may take longer than your usual appointments as you will need to make a plan to stay as healthy as possible and reduce the risk of harm during your future pregnancy.

You are making very important decisions at this meeting. Take your time and make sure you have all the information you need to make decisions. Your doctor will also talk to you about taking 5 milligrams of folic acid every day. This will help reduce the risk of your baby having neural tube defects such as spina bifida.

If you have epilepsy

Any changes to your medicine will include a neurologist (a doctor who is specially trained in treating problems that affect the brain, spinal cord and nerves). All the doctors looking after you will be working to:

  • make sure you do not take any more medicines than you have to, reducing the risks of harm to you and your baby
  • control your seizures as well as possible. 

If you do not have epilepsy and are taking antiepileptic medicines for other health conditions

Your doctor will be able to tell you if it is safe for you to stop taking your medicine or to take another medicine so there is less risk of harm for your baby and you.

The ACC website has some useful information about pregnancy, epilepsy and medication.

Women with mental illness, or who have had mental illness during or after an earlier pregnancy, have a higher chance than other women of developing mental illness during or after their current pregnancy.

What you need to do if you’re thinking about getting pregnant

If possible, it is best to plan pregnancies and speak with your GP, psychiatrist, mental health nurse or other health professional helping with your care before you get pregnant.

Some medications are not ideal in pregnancy, and you may need to plan for changing medications beforehand.

  • Make a plan with your health professionals as to how and where the best care for you would happen.
  • Once you are pregnant, it is important to find a midwife as early as possible in your pregnancy who you are relaxed and comfortable with, so you can discuss your mental health with them right from the start.
  • Your midwife will work with your mental health team to provide the best care for you.

There are also lots of resources available online.  

If you live with type 1 or 2 diabetes mellitus then you will probably be an expert at managing it well. 

If you are planning to get pregnant you should ideally speak with your GP, diabetes physician and/or diabetes nurse before trying to get pregnant, and get personalised advice and guidance to ensure optimal blood glucose control and health prior to conceiving.

Diabetes can mean a higher chance of your baby having birth defects, miscarriage and stillbirth so it is really important to plan your pregnancy and make sure you are as well as possible, with excellent blood glucose levels.

It is also really important to manage your blood sugar levels well throughout your pregnancy to reduce the likelihood of developing complications during your pregnancy.

You can find more information on the Diabetes New Zealand website and Ministry of Health website.

If you have had severe complications in a previous pregnancy or currently have severe or complex health conditions, and you’re planning to get pregnant, talk to your GP about what you will need to consider.

It is best to arrange to have this appointment 3-6 months before trying to conceive.

Previous severe pregnancy complications include:

  • history suggestive of cervical insufficiency such as preterm pre-labour rupture of membranes (PPROM) or premature births
  • spontaneous pre-term birth at less than 32 weeks of pregnancy
  • miscarriage in the second trimester
  • stillbirth or your baby passed away following birth.

If you currently have a complex health condition, it could significantly affect your pregnancy, your health during pregnancy, or the health of your baby.

After a discussion with your GP, they may refer you to hospital maternity services to be reviewed by an obstetrician (a doctor who specialises in pregnancy care). Your GP may receive advice to discuss or action with you, or you may be offered a pre-conception care appointment at a high-risk pregnancy clinic.
