These are the things you can do before pregnancy to make a difference to the health of your pregnancy and baby.

There are things you can do now before you try for a baby that will affect your fertility and the health of your baby.

Your health before pregnancy will affect the lifelong health of your baby. By following the advice below you can:

  • improve your fertility
  • protect your baby’s future health
  • bring down your risk of problems in pregnancy.

Once you start trying for a baby (have stopped contraception) you won't know you're pregnant for the first few weeks.

What to do

These are the things to do before pregnancy make your pregnancy and baby healthier.

1. Get help to stop smoking

Smoking affects fertility (the ability to get pregnant) in men and women. If you stop smoking now it will improve your chances of conceiving. Smoking has also been shown to damage the DNA of your baby. During pregnancy smoking is the biggest risk factor for serious complications in pregnancy that you can change.

Get support to stop smoking. 

2. Start taking folic acid now

Folic acid needs to build up in your body to provide maximum protection for your baby against neural tube defects. Many women conceive within one month of trying so it is ideal to start taking folic acid two months before you stop contraception. If you have already stopped contraception, start taking a 400mcg folic acid supplement daily  until you are 12 weeks pregnant.

Some women may be prescribed 5mg of folic acid.

3. Eat well

You can improve your fertility by eating a healthy, balanced diet. The best foods include wholegrain, unsaturated fats and vegetable proteins such as lentils and beans.

Your diet before and during pregnancy will also affect your baby’s development in the womb and their health in the future. A healthy diet for pregnancy is the same as a healthy diet for life.

A dietitian can help if you have a condition that requires specific diets or nutritional requirements, such as diabetes.

Find out more about your diet, fertility and pregnancy.

4. Reduce your caffeine intake

Research shows that consuming too much caffeine while you are trying to conceive can increase the risk of miscarriage. The research shows that this applies to both women and men. Too much caffeine in pregnancy has also been shown to be harmful to the developing baby.

If you’re planning to conceive, you and your partner should consider   limiting your caffeine intake to 200mg a day.

You can use our caffeine calculator (link) to check your caffeine intake.

5. Try to maintain a healthy weight

Your BMI (Body Mass Index) is a measure that uses your height and weight to work out if your weight is healthy. The ideal BMI before conception is between 18.5 and 24.9.

Being overweight

Having a high BMI (over 25) can reduce your fertility and increases the risk of complications in pregnancy. Being overweight can also contribute to fertility problems in men (links to dad’s health).

If you have a very high BMI (over 30) you may feel like it is an impossible task to reach the healthy range and you may have been struggling with your weight your whole life. Try not to lose heart, bringing your BMI a few points down the scale can make a big difference.There is professional support available if you need it.

Being underweight

If your BMI is in the underweight range (18.5 or less) it may affect your fertility and cause health problems during pregnancy. It may help to put on weight gradually with a healthy diet. There are many reasons why a person may be underweight. You GP can give you help and advice.

6. Stay active

Being active by doing regular, moderate exercise before and after you conceive will help your fertility as well as benefiting your pregnancy and baby in the long term. Women who are physically active are more likely to have children who are physically active too.

The Department of Health recommends:

  • at least 150 minutes of moderate aerobic activity a week and
  • strength exercises on two or more days a week that work all the major muscles

Find out more about physical activity and planning a pregnancy.

7. Stop drinking alcohol 

Excessive or binge drinking is defined as regular consumption (drinking) of alcohol above recommended levels. Excessive drinking is linked to reduced fertility in both men (link to dad’s health) and women. 

Drinking alcohol in pregnancy increases the risk of complications. This is especially true during the first three months of pregnancy as this is when the baby’s brain is developing. You will not know when you are pregnant and that’s why the recommendation is that the safest thing to do is not drink any alcohol at all if you’re actively trying for a baby. It can be very difficult for some people to stop drinking alcohol. There are advice and treatment services available if you need support.

8. Don’t take non-prescription, recreational drugs

Non-prescription, recreational drugs, such as cannabis or cocaine can contriibute to fertility problems for men and women. Illegal drugs can also cause serious complications in pregnancy. It can be very difficult for some people to stop taking drugs. There are advice and treatment services available if you need support.

Find out more about illegal drugs and getting pregnant

9. Have a cervical screening test

If you are aged between 25 and 49 you should have a cervical screening test every three years. It’s best to get tested before you get pregnant because pregnancy can make the results of your test harder to interpret.

If you’re planning a pregnancy contact your GP surgery to find out if your screening is due now or within the next year. 

Find out more about cervical screening tests.

10. Check you have had your MMR vaccination

MMR stands for Measles, Mumps, Rubella. Rubella is rare, but can be very dangerous to a baby’s development, especially during the early stages of pregnancy.

The MMR vaccination will protect you and your baby. It is normally given to children in two injections before they reach 6 years of age.

If you have not been vaccinated or are unsure whether you have been vaccinated call your GP practice to see if they have a record. If you have no record of them, make an appointment to get vaccinated. Even if you had them before getting them again is not harmful.

Find out more about MMR vaccinations.

11. Have a sexual health check-up if there’s a reason to believe you may have an STI

Sexually transmitted infections can affect your fertility, as well as any future pregnancy and baby.

If there is any reason to think you or your reproductive partner may have a STI, it’s important that you both get tested. The best places to go are a GUM clinic, sexual health clinic, your own doctor or a young people’s clinic.

Find out more about sexually transmitted infections and conception

12. Talk to your doctor about any pre-existing conditions, any medications you are taking or previous pregnancy complications

Talk to your GP or specialist healthcare professional if you are planning to conceive and have any known, long-term medical conditions for which you take medication, such as epilepsy, diabetes, asthma or mental health conditions.

Some conditions and the medications used to treat them may impact on your ability to get pregnant. There may also be some risks associated with your condition or the medication used to treat them and pregnancy.

It is important not to stop taking medication before talking to a doctor or specialist about your plans to conceive. They will discuss the safest options for pregnancy with you.

    How can I tell if I'm going in early labor at 9 months

  • By Anonymous (not verified) on 24 Jan 2019 - 19:32

    I️ had unprotected sex two days before I️ ovulated, and he ejaculated in me. Is there a good chance I’m pregnant?

  • By Midwife @Tommys on 25 Jan 2019 - 15:50

    Yes there is a chance you could be pregnant. If your next period does not come when due, then we would suggest taking a test. Taking a test earlier than this make result in a false negative result. If you think you may be pregnant or if you are trying for a baby, then we would advise you to be taking a daily folic acid supplement if you are not already.

  • By Midwife @Tommys on 25 Jan 2019 - 15:49

    Hi Jane,
    It sounds like you would benefit from a referral to a fertility specialist so they can carry out some tests and investigations to see if they can help you conceive.

    We have a 18 month old son together. He wasnt planned and was a shock.
    We have been trying for a year now.
    He was always away all week back weekends and now he's away 3 weeks at a time.
    I'm getting worried we just won't be able to conceive another child.
    I don't want our Son to be at school full time when it happens as want a nice closer gap.
    Any recommendations?
    I'm nearly 32

  • By Martha (not verified) on 15 Mar 2018 - 23:01

    Hi i had sex around my ovulation period for 2 cycles and i am still not pregnant. What would you advise.

  • By Midwife @Tommys on 16 Mar 2018 - 15:57

    Thank you for your comment. I would advise that you keep trying; it may be an idea to use an ovulation predictor if you are not already using one.
    It's also recommended to have regular sex throughout your cycle not just around ovulation as this is the best way to increase your chances of conception.
    Also make sure you have a healthy diet, continue to exercise, stop smoking and drinking alcohol, limit caffeine intake, take folic acid supplements(400mcg a day) and maintain a healthy weight.

    It may take a while to conceive but 80% of couples will do so within a year.
    I have attached some links that you may find helpful

    Hiya me and May partner have been trying to get pregnant just over a year now. I had an exctopic pregnancy a couple of years ago and I was worried about any damage it may have caused. I was told I am ovulating just fine still and to try not to worry too much. Have u any advice at all that may help me please

  • By Midwife @Tommys on 26 Oct 2017 - 15:25

    Hi, Thank you for your comment.

    Please feel reassured that it can take some couples up to a year to conceive but with your past medical history, it is understandable that you are feeling worried. As you have been trying to conceive for over a year it would be advisable that you and your partner make an appointment and speak to your GP, they will be able to offer your advice on what to do next, they may offer you tests or even make a referral to a specialist if this is needed. Please try not to worry, this can be normal for some couples but seeing the GP will help. Take Care, Tommy's Midwives x

    myself and my husband being try for baby for about 7mouths now and we just want to no if we are doing it at the right time

  • By Midwife @Tommys on 4 Oct 2017 - 11:36

    Hi, Thankyou for your comment.

    It can be normal for it to take a few months to conceive when you have just started trying, this doesn't mean that there is anything wrong, it can just take some time. If you have a regular cycle and your periods are regular then on average a women would ovulate around day 14 of this cycle, so 14 days after the first day of your last period. If you want to work out these dates, we do have an ovulation calculator on the Tommy's website, where you can put the date of your period in and then it will tell you when you should be ovulating. Having sex around this time can optimise your success of conception, but also having unprotected sex throughout your cycle can help as well. If you are still not getting pregnant then then next step would be to see the GP who may refer you to a specialist for help and advice, this is nothing to be concerned about, it is just what we recommend after months of trying for a baby. Hope this helps, Tommy's Midwives x
