Amenorrhoea is the medical term for missed, late or stopped periods.

If this happens, it’s natural to be worried. While every woman’s menstrual cycle is different, if you’re at all concerned, our online doctors can help you find out why your periods are delayed. Whatever the reason, they’ll provide confidential, discreet advice and support in the comfort of your own home.

Any change to your normal menstrual cycle could be a symptom of amenorrhoea.

In particular, you should see a doctor if your periods have stopped and you've had a negative pregnancy test.

There are a number of potential reasons why your period might have been delayed, missed or different from normal. The most common causes include:

Pregnancy - If you’ve been sexually active recently, it may be that the contraception you used hasn’t worked.
Contraception - Some forms of contraception can cause periods to become irregular or stop altogether.
Stress - There are a number of ways stress can impact your physical health and this includes your menstrual cycle. Too much stress can cause periods to become irregular.
Being overweight - If you’re overweight or obese, your body may produce too much oestrogen, one of the hormones that regulates your menstrual cycle. This can delay or stop your menstrual cycle.
Being underweight - If you’re severely restricting your calorie intake and/or exercising intensively, your weight loss could cause a hormonal imbalance that affects your menstrual cycle.
The menopause - Periods stopping is a natural part of the menopause and can be one of the early signs that it’s starting. Most women experience the menopause from the age of around 45.
Polycystic ovary syndrome (PCOS) - Thought to affect around 1 in 10 women, this condition prevents your ovaries releasing an egg.

Any treatment or support for your missed or late period will be focused on the underlying cause.

For example, if you’re going through the menopause or pregnant, our doctors will provide all the support you need. If weight problems are contributing to your amenorrhoea, our doctors can give you advice on how to lose or gain weight safely.

If necessary, our doctors can refer you to a specialist for further tests.

Amenorrhoea is the medical name given to missed or late periods. It can occur for a variety of reasons, including pregnancy, menopause or an underlying medical condition.

Our doctors can help you find out the cause and suggest practical next steps. If treatment is needed, they can provide a prescription or specialist referral.
