Is period pain normal? When should you see a doctor?

Mild, short-lived period discomfort is very common. But period pain that gets in the way of daily activities, school or work, that painkillers do not relieve enough, or that keeps getting worse should not be treated as “normal”. Such pain can be a sign of treatable causes, including endometriosis, and is worth discussing with a doctor.

Why is “it’s normal” said so often?

The World Health Organization notes that in many countries both the public and front-line health workers do not know that severe pelvic pain is not normal, which leads to normalisation and stigma of symptoms and to delays in diagnosis. So being told “everyone goes through it” does not mean your pain should not be assessed.

Which patterns deserve attention?

• Missing school or work, or cancelling plans because of pain.
• Painkillers not being enough.
• Pelvic pain that continues outside your period.
• Deep pain during sex.
• Bowel or urinary symptoms around your period.

The NICE guideline advises suspecting endometriosis when period pain affects daily activities and quality of life. The ESHRE guideline also lists dysmenorrhoea, deep dyspareunia, bowel and urinary symptoms and difficulty getting pregnant among symptoms that should make a doctor consider endometriosis.

Does pain mean endometriosis?

No. Severe period pain has other causes, and only a doctor can assess it. ESHRE says the evidence for predicting endometriosis from symptoms alone is weak, but that reporting several symptoms together raises the likelihood.

What can you do?

1. Note your pain and when it happens over a few cycles.
2. Fill in the symptom checklist and print the summary.
3. See a doctor, ideally a gynaecologist. Take a look at our article on preparing for your appointment.
4. If the answer stays “it’s normal” and your symptoms continue, you are entitled to ask for a second opinion.
