PERIOD HEALTH · THE CONDITIONS

When pain has a name.

Pain that disrupts your life isn't just “bad periods”. Seven conditions cause most of it — and every one has a name, a pattern, and a path forward.

Read them like profiles,
not like diagnoses.

i · THE PROFILES

Meet them properly.

Pick a condition — the profile, the numbers, and the symptom overlap below all follow along.

CONDITION 1 OF 7

Endometriosis

Tissue similar to your uterine lining, growing where it shouldn't.

Patches of tissue similar to the lining of your uterus grow outside it — on the ovaries, pelvic walls, sometimes the bowel or bladder. Each cycle, those patches respond to your hormones like the lining does: they thicken, break down, and bleed. But that blood has nowhere to go, so it inflames and scars the tissue around it. The result is pain that often starts before your period and can long outlast it.

PEOPLE WITH PERIODS ARE AFFECTED

7–10 yrs

AVERAGE WAIT FOR A DIAGNOSIS

ITS SIGNATURE

  • 01Period pain that painkillers barely touch, often starting days before bleeding
  • 02Deep pain during or after sex
  • 03Painful bowel movements or urination, worse on your period
  • 04Fatigue, and sometimes difficulty getting pregnant

SAY THIS TO YOUR DOCTOR

My period pain regularly stops me from working or sleeping, and it's getting worse. I'd like to be assessed for endometriosis.

WHERE IT LIVES

Outside the uterus — ovaries, pelvis, bowel, bladder

TENDS TO SHOW UP

Any age after periods begin; often dismissed for years

HOW IT'S FOUND

Symptom history plus ultrasound or MRI; laparoscopy confirms

WHAT HELPS

Hormonal therapy, excision surgery, specialist pain care

Seven different causes — but their symptoms overlap.
That's exactly why diagnosis takes so long.

ii · THE OVERLAP

Same symptoms, different causes.

Find the symptom that bothers you most, and see which conditions it points toward.

SYMPTOMS OF

Endometriosis

HALLMARK

  • Severe cramping or pelvic pain
  • Pain during or after sex
  • Fatigue or anemia

SOMETIMES PRESENT

  • Very heavy or prolonged bleeding
  • Pelvic pressure, bloating, or fullness
  • Sudden, severe one-sided pain

Endometriosis's tell: pain that leads the period — starting before bleeding, and touching sex, bowel, and bladder.

This is for pattern-spotting, not self-diagnosis. Several of these conditions can also exist together — one more reason a proper work-up matters.

iii · THE NEXT STEP

Walk in prepared.

Diagnosis moves faster when you arrive with evidence. Two weeks of notes beats a year of "it just hurts."

BEFORE YOU GO

Track for two cycles

  • Pain: which days it hits, how bad (0–10), and what it stops you doing — work, sleep, exercise.
  • Flow: how often you change protection on heavy days, and any flooding or clots.
  • The calendar: cycle start dates and length — irregularity is data too.
  • Mood: note which days feel unmanageable, not just “bad”.
  • What you've tried: painkillers and doses, heat, and whether they actually worked.
IN THE ROOM

Five questions to ask

  • 01Which of these conditions could explain my symptoms?
  • 02What tests would rule them in or out — and can we start with an ultrasound?
  • 03Could more than one thing be going on at once?
  • 04If treatment doesn't help within a few months, what's the next step?
  • 05At what point would I be referred to a gynecologist?

If you're dismissed with “that's just periods” while your pain keeps disrupting your life — it's okay to ask for a referral, or a second opinion.

not sure if something's wrong?

If any of these conditions sound familiar, it's worth knowing when to act, and how urgently.
