• Our symptom checker only asks about whether you experience heavy bleeding and/or period pain, but you may experience other symptoms in relation to your period, or no symptoms at all. If you're looking for information about periods not related to heavy bleeding or period pain, visit our periods hub.
• This checker is not to be used if you have irregular periods and bleed fewer than four times a year, in which case please see your GP. If you have other changes such as bleeding in between your periods or after sex, please see your GP.
• This checker will not diagnose you. It will help you decide if you need to see a doctor, help in discussions with your doctor, and it will also give helpful information about periods.
• Always speak to your doctor if you have concerns about your health.

About

Our symptom checker has been developed in partnership with GPs, gynaecologists, pharmacists and women to help tackle normalisation of period-related symptoms and empower you to seek the correct advice.

Too many women are being held back by their periods unnecessarily. In less than five minutes, you can find out if your period symptoms are something you should contact your healthcare professional about. You can receive a letter personalised with your symptoms to give to your GP - to help start the conversation.

If you already have a diagnosis of endometriosis, adenomyosis, fibroids or another gynaecological condition and you've developed any new symptoms, or your symptoms have become worse, please speak to your doctor.

This symptom checker is for people aged 16 or over. It is not designed to be filled in on behalf of someone else. If you're worried about someone else with symptoms, please share this symptom checker with them.

The results from this symptom checker should not replace advice from your healthcare professional.

“Just a Period” 

Nobody should suffer from period symptoms holding them back.

We want to educate and empower girls and women to be in control of their menstrual health from their first period to their last.
