When to see your GP

It's normal to experience mild PMS symptoms in the two weeks before your period starts. However, you should see your GP if the symptoms are making everyday life difficult.

Your GP may ask you to use a diary to record how you're feeling each day in the run-up to your period.

You may have to do this for at least two or three months so your GP canspot any patterns in your symptoms.

PMDD is only diagnosed when your mood symptoms seriously affect your relationships and stop you functioning properly at work or school.

Your GP may refer you to a mental health specialist for further assessment and treatment if they think you have PMDD.
