Endometriosis: When Period Pain Isn't Just Period Pain
Endometriosis is one of the most commonly delayed diagnoses in women's health — often 7 to 10 years from first symptoms. Being dismissed isn't the same as being fine, and severe period pain that disrupts your life is exactly the kind of “common” that isn't actually normal.

What it actually is
Endometriosis is tissue similar to the uterine lining growing outside the uterus — often on the ovaries, fallopian tubes, or pelvic lining, sometimes beyond. That tissue still responds to your hormonal cycle each month, which causes inflammation, scarring, and pain in a way that regular uterine lining tissue, safely contained inside the uterus, doesn't.
Why it's so often missed
Painful periods get normalized constantly — “that's just how periods are” — so the pain that's actually a sign of endometriosis often goes unrecognized for years. Symptoms can also be subtle, inconsistent, or overlap with other conditions like IBS, which adds to the delay.
Common signs
Pelvic pain — often but not always tied to your period — pain with intercourse, pain with bowel movements or urination (especially during your period), heavy periods, fatigue, and difficulty conceiving are the signs most associated with endometriosis. Severe period pain that limits your daily activities is not something to just push through.
How it's diagnosed
History and a pelvic exam are the starting point. Imaging like ultrasound (sometimes MRI) can suggest endometriosis, but it often looks completely normal even when endometriosis is present — a normal scan doesn't rule it out. Laparoscopic surgery is the only way to definitively diagnose and stage it, though many providers now start treatment based on your symptoms and history without requiring surgery first.
How it's managed
Hormonal treatments — birth control, progestins, or GnRH agonists — suppress the cycle and can slow progression and reduce pain. Pain management and pelvic floor physical therapy often help alongside hormonal treatment. Surgery (excision) is an option for more severe cases, or when fertility is a priority and the disease may be affecting it.
