If you have been trying to get pregnant for quite a while and haven't yet been successful, it can come as quite a shock to discover that you are infertile.
And if you are over 30 this whole thing can suddenly seem very worrying.
But the good news is that more women than ever are having a baby in later life.
And although your fertility has waned as you've grown older, it is still possible to increase it by making certain changes to your lifestyle.
To begin with you will need to pay some attention to your diet.
You need to make sure you are eating a healthy, nutritious diet that contains all the vitamins and minerals you need and that you are getting plenty of folic acid.
This usually means taking a supplement.
There are other important changes that you will need to make, especially when you're in your thirties or forties.
Get your body weight checked at your local clinic.
If you are overweight or underweight this can also hinder your chances of getting pregnant.
If your weight needs to be adjusted your local health adviser will help you form an eating plan that will allow you to reach a weight that is right for you.
If you are a smoker or if you drink alcohol or take any recreational drugs this will also drastically reduce your chances of conceiving a baby.
It's important to stay hydrated by drinking the recommended daily amount of water, but drinks that contain caffeine should be avoided.
Your partner should also make sure he maximises his fertility by following a healthy diet that includes zinc.
This is probably the most important mineral for boosting male fertility.
By making all these changes you may find you will soon become pregnant, even in you're in your thirties or older.
