What are the main symptoms of endometriosis?

Common symptoms include painful periods that may worsen over time, chronic pelvic pain, pain during or after sex, painful bowel movements or urination (especially around the period), heavy periods, bloating, fatigue, and difficulty conceiving. Symptoms vary widely between individuals and do not always match the amount of endometriosis present. Because period pain is often normalised, keeping a detailed symptom diary across cycles helps ensure the pattern is recognised and taken seriously.

Why does endometriosis take so long to diagnose?

Diagnosis is often delayed by several years for a few reasons: period pain is frequently dismissed as normal, symptoms overlap with conditions like IBS, and imaging scans can appear normal even when endometriosis is present. Definitive diagnosis has traditionally required laparoscopy (keyhole surgery). A clear, detailed symptom history is therefore crucial, and it is reasonable to ask your doctor directly whether endometriosis could explain your symptoms and what the next steps are.

Can a normal ultrasound rule out endometriosis?

No. Ultrasound and even MRI can detect some forms of endometriosis, such as ovarian endometriotic cysts, but they often appear normal in superficial or early disease. A normal scan therefore does not exclude endometriosis. This is why your symptom history is so important, and why laparoscopy has been the definitive way to confirm the diagnosis — though treatment is increasingly started based on clinical suspicion rather than waiting for surgery.

How is endometriosis treated?

Treatment is individualised and may include pain relief (such as anti-inflammatories), hormonal treatments (the combined pill, progestogens, or other hormonal options) to reduce symptoms, and laparoscopic surgery to remove endometriosis tissue. If fertility is affected, fertility-focused care may be offered. Many people benefit from a multidisciplinary approach including pain management. The right combination depends on your symptoms, their severity, and your fertility plans, which is why discussing your priorities is important.

Preparing for Appointments with Endometriosis

Quick answer: Track your symptoms across at least two menstrual cycles — pain (where, when, how severe), its relationship to your period, bowel and bladder symptoms, pain during sex, and the impact on daily life. Endometriosis is often under-recognised and the average time to diagnosis is years, so a detailed symptom diary helps you be heard. Note what painkillers you have tried and how well they worked, and bring any previous scan or surgery results.

Endometriosis is common and frequently dismissed, with diagnosis often taking years. The most powerful thing you can do is document your symptoms clearly across cycles and insist they be taken seriously. A precise pain-and-cycle diary turns ‘bad periods’ into a pattern a clinician can act on.

What to Track Before Your Appointment

Pain: location, severity (0–10), timing relative to your period, and whether it is getting worse. A appointment notebook or a period-and-pain app is ideal.
Cycle: dates, flow, and how symptoms map onto it
Associated symptoms: pain during or after sex, painful bowel movements or urination (especially around your period), bloating, fatigue
Fertility: whether you are trying, or planning, to conceive
What you have tried: painkillers, hormonal treatments, and how well each worked

Why Diagnosis Is Often Delayed

Period pain is often normalised, symptoms overlap with other conditions, and scans can look normal even when endometriosis is present. This is why your detailed history matters so much — and why it is reasonable to ask directly, ‘Could this be endometriosis?’ A normal ultrasound does not rule it out.
