If you are planning a pregnancy there are a number of steps you can take to help improve your chances of getting pregnant and having a healthy pregnancy.
Take a folic acid supplement
It's recommended that you should take a daily supplement of folic acid when you're pregnant, or there's a chance you might get pregnant.
You should take a 400 microgram supplement of folic acid every day before you get pregnant, and every day afterwards, up until you're 12 weeks pregnant.
You can get folic acid tablets at pharmacies, or talk to a GP about getting a prescription.
Do not worry if you get pregnant unexpectedly and were not taking a folic acid supplement at the time. Start taking them as soon as you find out, until you're past the first 12 weeks of pregnancy.
Stop smoking
Smoking during pregnancy has been linked to a variety of health problems, including:
Quitting can be hard, no matter how much you want to, but support is available.
NHS Smokefree offers free help, support and advice on stopping smoking, including when you're pregnant, and can give you details of local support services.
Smoke from other people's cigarettes can damage your baby, so ask your partner, friends and family not to smoke near you.
Cut out alcohol
Do not drink alcohol if you're pregnant or trying to get pregnant. Alcohol can be passed to your unborn baby.
Drinking in pregnancy can lead to long-term harm to your baby, and the more you drink, the greater the risk.

Keep to a healthy weight
If you're overweight, you may have problems getting pregnant and fertility treatment is less likely to work.
Being overweight (having a BMI over 25) or obese (having a BMI over 30) also raises the risk of some pregnancy problems, such as high blood pressure, deep vein thrombosis, miscarriage and gestational diabetes.
Having a healthy diet and doing moderate exercise are advised in pregnancy, and it's important not to gain too much weight.
You can keep to a healthy weight by having a balanced diet and doing regular exercise.
