If you have painful periods, ongoing pelvic pain, or pain during sex, it can be difficult to know what is causing it. At a specialist visit, a gynecologist will listen to your symptoms, review your health history, and discuss whether endometriosis or another condition may be responsible.

You may not leave the first appointment with a definite answer. That does not mean your symptoms are being ignored. Diagnosis can involve several steps, and your clinician may start with a likely diagnosis and a care plan while arranging further tests.

What is endometriosis?

Endometriosis is a condition in which tissue similar to the lining of the uterus grows outside it. These areas are often found around the uterus, ovaries, fallopian tubes, or pelvic lining. In some people, endometriosis also affects the bowel or bladder. Symptoms vary: some people have severe pain, while others have few or no symptoms.

Symptoms that may lead someone to seek an evaluation include:

• Period pain that disrupts everyday activities
• Ongoing pain in the lower abdomen or pelvis
• Pain during or after sex
• Pain when urinating or having a bowel movement
• Heavy periods or unusual bleeding
• Fatigue or difficulty getting pregnant

These symptoms can also happen with other conditions, such as adenomyosis, fibroids, pelvic inflammatory disease, or irritable bowel syndrome. Your specialist will consider the full picture rather than relying on symptoms alone.

Before your appointment

A few notes can help you explain what you have been experiencing. You might record when pain happens, how long it lasts, whether it changes around your period, and how it affects work, sleep, relationships, or daily activities. Note symptoms such as bowel or bladder pain, bleeding, nausea, or fatigue, along with any treatments you have tried and whether they helped.

Bring a list of medications and supplements, and mention any previous diagnoses or surgeries. If a close relative has endometriosis, tell the specialist. You can also write down your questions beforehand so you do not have to remember everything during the visit.

You do not need to have a complete symptom diary to attend. Share what you can, in your own words.

What happens during the first visit?

The specialist will usually begin by asking about your symptoms and medical history. They may ask when the symptoms began, whether they follow a monthly pattern, and whether they are getting worse. They may also ask about your periods, previous treatments, family history, and whether pregnancy is something you are considering now or in the future.

These questions help the specialist understand how your symptoms affect you and what investigations may be useful. Endometriosis can affect different people in different ways, so details that may seem small to you can still help guide the evaluation.

Your specialist may offer a physical examination, which can include an abdominal or pelvic exam. An internal examination is not automatic or the only way to assess your symptoms. If one is suggested, ask what it involves and why it may help. You can discuss your concerns, ask for a chaperone, or ask the clinician to pause or stop. The examination should be explained to you before it begins.

Can symptoms and an exam lead to a diagnosis?

Yes, sometimes a specialist can make a presumptive clinical diagnosis based on your symptoms, medical history, and examination findings. In 2026, the American College of Obstetricians and Gynecologists (ACOG) issued updated guidance supporting this approach. A clinical diagnosis can help a clinician discuss treatment while further evaluation, including imaging, continues.

This matters because surgery is not always needed before a clinician can discuss symptom management. Your specialist may explain how confident they are in the suspected diagnosis and what additional information would help. You can ask what the diagnosis means for your care and what the next step will be.

Imaging tests you may be offered

A pelvic ultrasound uses sound waves to create images of the pelvic organs. It may be done over the abdomen or with a probe placed inside the vagina. A transvaginal ultrasound can provide a closer view, but you can ask questions about the procedure before deciding whether to have it.

An MRI uses magnetic fields and radio waves to create detailed images. A clinician may recommend one when more information is needed (including to look for certain forms of endometriosis or help plan treatment). Ultrasound and MRI can identify some larger areas, such as cysts or nodules, but they may not show small lesions or adhesions. A normal scan therefore does not rule out endometriosis.

Your specialist may recommend imaging before discussing surgery, or arrange it as part of a broader evaluation. The choice depends on your symptoms and what the clinician needs to assess.

Will I need surgery to confirm endometriosis?

A procedure called laparoscopy allows a surgeon to look inside the abdomen and pelvis using a small camera inserted through a small incision. It may be used to investigate suspected endometriosis, and areas of endometriosis may sometimes be treated during the same procedure. It involves surgery and anesthesia, so your clinician should explain its possible benefits, risks, and alternatives.

Your doctor may suggest laparoscopy if your symptoms persist, other tests do not explain the cause, or the procedure could help them choose the right treatment. A normal ultrasound or MRI does not necessarily mean laparoscopy is off the table if endometriosis is still suspected. Equally, a first specialist appointment does not mean you will automatically be offered surgery. The decision should be based on your situation and made with your input.

What might happen after the appointment?

Depending on your symptoms and findings, the specialist may:

• Arrange an ultrasound or MRI
• Discuss symptom-relief options while the evaluation continues
• Refer you to another specialist if bowel, bladder, fertility, or other concerns need attention
• Schedule a follow-up to review test results and next steps
• Discuss whether laparoscopy is appropriate

You should leave knowing how to get your results, who will contact you, and when to follow up. If those details are unclear, ask before the appointment ends.

Questions you can ask

Consider asking:

• What findings make you think endometriosis may be causing my symptoms?
• What other conditions could cause similar symptoms?
• What will the scan or examination help determine?
• If my scan is normal, what happens next?
• Can we discuss symptom treatment while testing continues?
• What are the benefits and risks of laparoscopy in my case?
• When should I expect to hear about test results?

Your symptoms deserve attention

Endometriosis can take time to diagnose because its symptoms overlap with other conditions. A careful first visit can begin the process: your history, symptoms, examination if appropriate, and imaging all help build a clearer picture.

If pelvic pain or period symptoms are affecting your daily life, consider booking an appointment with a gynecologist or endometriosis specialist. Bring your questions and share what you have noticed. You are an important part of decisions about your evaluation and care.
