Endometriosis Symptom Checker

Endometriosis is a condition in which tissue similar to the lining of the uterus grows outside the uterus — for example on the ovaries, fallopian tubes, or other pelvic organs. Each cycle this tissue responds to hormones the way the uterine lining does, which can cause inflammation, pain, and scarring. It most commonly causes painful periods, chronic pelvic pain, pain with sex, and difficulty getting pregnant. It is a common condition and often under-recognized, in part because its symptoms overlap with ordinary period pain and other pelvic conditions. It's a real, treatable medical condition — not something you're meant to simply endure.

The most common are painful periods (dysmenorrhoea) — cramping that can be bad enough to interfere with daily life — and chronic pelvic pain at other times of the month. Others include deep pain during or after sex (dyspareunia), painful bowel movements or urination that are often worse around your period, heavy menstrual bleeding, and difficulty getting pregnant. Symptoms vary a lot from person to person, and how severe they feel doesn't necessarily match how much endometriosis is present — some people with a lot of pain have little, and some with little pain have a lot. Importantly, symptoms don't have to be severe to matter.

Not on its own. This checker reads a symptom pattern, and a match means the pattern is reasonable to discuss with a gynecologist — not that you have endometriosis. These symptoms are common and have many possible causes: fibroids, ovarian cysts, pelvic inflammatory disease, irritable bowel syndrome, and others can all look similar, and PCOS can overlap too. Only a clinician can work out which one fits, using your history, an exam, and sometimes imaging or surgery. So take a match as a good reason to raise it — and a negative result as reassuring on this check but never a way to rule endometriosis out.

A gynecologist starts with your symptom history and a pelvic exam, and may order imaging such as an ultrasound or MRI. Imaging can find some endometriosis — like ovarian cysts called endometriomas — but it often looks completely normal even when endometriosis is present, so a normal scan does not rule it out. The definitive way to confirm endometriosis is laparoscopy: a minor keyhole surgery in which a clinician looks inside the pelvis directly (and can treat what they find). One reason diagnosis is so often delayed — the World Health Organization notes it commonly takes several years, on the order of 4 to 12 — is that symptoms are variable and are frequently dismissed as normal period pain. You don't need a confirmed diagnosis to start talking about pain relief and options.

Sudden, severe pelvic pain — especially with a fever, fainting, or feeling lightheaded — is not what this checker is for and should be treated as urgent. It can be a sign of an emergency such as ovarian torsion (a twisted ovary that can cut off its blood supply) or an ectopic pregnancy, both of which need immediate care. If you have pain like that, go to urgent care or an emergency room now, or call your local emergency number. This tool is for ongoing, cyclical symptoms — not for acute severe pain, which always warrants prompt in-person evaluation.

It's general educational information based on ACOG, WHO, and MedlinePlus patient guidance; it can't diagnose you, isn't a test, and doesn't replace an evaluation by a licensed clinician.
