If period pain is disrupting school, work, sleep, or time with people you care about, you deserve a conversation about it. Endometriosis is one possible explanation among several; symptoms alone cannot tell you which condition is responsible.
The World Health Organization explains endometriosis as a condition in which tissue similar to the lining of the uterus grows outside it. Symptoms can include severe period pain, ongoing pelvic pain, pain during sex, and difficulty getting pregnant. Experiences vary, and some people have no symptoms.
For an appointment, describe when pain happens, how bleeding has changed, and which everyday activities are affected. A short written record can make that conversation easier. You do not need to label the problem yourself before asking for an assessment.
Our background guides below explain cycle terminology, offer a printable symptom tracker, and help you prepare questions about tests. They are not dedicated endometriosis guides and do not establish a diagnosis. For a condition-specific overview of assessment and care, start with the linked WHO resource. The related topics provide additional routes into questions about periods and fertility.
