1. Cyclical pelvic pain
The cardinal symptom. Severe dysmenorrhoea (painful periods) progressing in intensity over years. Pain often starts in mid-cycle (ovulation), peaks during menstruation, may continue several days. Can radiate to back, thighs. Disrupts work, school, daily life. Severity progression — 7/10 last year, 9/10 this year — is a major clue.
2. Deep dyspareunia
Pain during deep penetration in intercourse. Particularly suggestive of pouch of Douglas disease, uterosacral nodules, or deep infiltrating endometriosis. May limit positions. Often unmentioned by patients out of embarrassment. Should be explicitly asked about in any endometriosis evaluation.
3. Cyclical bowel symptoms
Bowel symptoms tied to menstrual cycle suggest endometriosis. Cyclical bloating, abdominal pain with menstruation, dyschezia (painful defecation during periods), cyclical diarrhoea or constipation, occasional rectal bleeding during periods. Often misdiagnosed as IBS. Cyclical pattern is the key differentiator.
4. Cyclical urinary symptoms
Less common but specific. Cyclical dysuria, frequency, urgency tied to menstruation. Recurrent cystitis-like symptoms but cultures negative. Bladder pain during periods. Suspect bladder endometriosis. Cyclical haematuria is highly suggestive though uncommon.
5. Chronic pelvic pain
As disease progresses, cyclical pain becomes constant baseline pain with cyclical exacerbations. May extend beyond menstruation throughout cycle. Often accompanied by pelvic floor dysfunction (secondary muscle tension). Quality changes from cramping to dragging, aching, sharp depending on lesion type.
6. Subfertility
30-50 percent of endometriosis patients experience subfertility. Mechanisms — anatomic distortion, ovarian damage from endometriomas, impaired implantation, inflammatory effects on tubal function, sperm-egg interaction. Often the trigger for diagnosis in undiagnosed patients (workup reveals endometriosis).
7. Fatigue and systemic symptoms
Chronic fatigue from inflammation, pain, sleep disruption. Brain fog. Decreased exercise tolerance. May relate to anaemia from heavy menstrual bleeding. Mood disturbances from chronic pain. Often dismissed as unrelated but is part of the syndrome.
8. Symptoms by stage
Symptom severity does NOT correlate well with disease stage. Some women with severe stage IV disease have minimal symptoms; others with stage I have severe symptoms. Symptom pattern (cyclical, progressive, multi-site) is more predictive than stage. Trust the symptoms — investigate even when imaging is unremarkable if pattern fits.

Eight key symptoms — and what they may indicate
| Symptom | What it may point to |
|---|---|
| Severe period pain (dysmenorrhoea) | Active disease, possible deep involvement |
| Deep pain with intercourse | Uterosacral or rectovaginal disease |
| Cyclical painful bowel movements | Bowel / rectovaginal endometriosis |
| Cyclical painful urination | Bladder endometriosis |
| Chronic (non-cyclical) pelvic pain | Established or widespread disease, central sensitisation |
| Heavy or irregular bleeding | Coexisting adenomyosis |
| Difficulty conceiving | Tubal/ovarian involvement, inflammation |
| Cyclical fatigue & bloating | Systemic inflammatory burden |
