Pelvic pain — discomfort low in the belly, below the navel and between the hips — is common in women and has many possible causes, most of them not dangerous. It can come from the reproductive organs, the bladder and urinary tract, the bowel, or the muscles and nerves of the pelvic floor. This is a plain-language reference to the more common causes and the warning signs that mean you should get help now.

When to get urgent care

Most pelvic pain can wait for a routine appointment, but some patterns need same-day or emergency attention. Seek emergency care (call your local emergency number or go to the ER) if you have:

  • Sudden, severe pelvic pain, especially on one side, or pain that doubles you over.
  • Pain with fainting, dizziness, a racing heart, or feeling you might pass out.
  • Pelvic pain when you are or could be pregnant — particularly with vaginal bleeding or shoulder-tip pain, which can signal an ectopic pregnancy.
  • Pain with a fever, chills, or a foul-smelling vaginal discharge, which can point to a serious infection.
  • Heavy vaginal bleeding, or any vaginal bleeding after menopause.
  • Pain with repeated vomiting, a rigid or very tender belly, or being unable to pass urine or stool.

Book a non-urgent appointment soon if pain is ongoing, keeps coming back, disrupts daily life, or comes with pain during sex, periods that are getting more painful, or a change in your usual bladder or bowel habits.

Possible causes

The list below is neutral — these are possibilities to discuss with a clinician, not a diagnosis. Where pain starts, how it behaves across the month, and what comes with it all help narrow things down.

Menstrual and ovulation pain

Cramping before and during a period (dysmenorrhea) is one of the most common causes. A brief, one-sided twinge around mid-cycle (ovulation pain, or mittelschmerz) is also normal for many women. Pain that is severe, worsening, or new later in life deserves review rather than being written off as "just periods." See menstrual health for more.

Ovarian cysts

Fluid-filled sacs on an ovary are very common and often cause no symptoms, but a larger cyst can bring a dull ache, bloating, or pressure. Sudden severe pain can occasionally mean a cyst has ruptured or twisted the ovary (torsion), which is a surgical emergency.

Fibroids and adenomyosis

Fibroids are non-cancerous growths in or around the womb; adenomyosis is womb-lining tissue growing into the muscle wall. Both can cause heavy periods, a sense of pelvic pressure, and cramping.

Endometriosis

Tissue similar to the womb lining grows elsewhere in the pelvis, causing pain that often tracks the menstrual cycle, pain during or after sex, and sometimes bowel or bladder symptoms. Diagnosis is frequently delayed, so persistent cyclical pain is worth raising directly.

Urinary and pelvic infections

A urinary tract infection typically brings burning on urination and needing to go often. Pelvic inflammatory disease (PID) — infection of the upper reproductive organs, often from a sexually transmitted infection — can cause lower pelvic pain, unusual discharge, fever, and pain during sex, and needs prompt treatment to protect fertility.

Bowel and digestive causes

Irritable bowel syndrome (IBS) causes recurring lower-abdominal pain linked to bowel habits, along with bloating and relief after a bowel movement. Constipation, diverticular disease, and celiac disease can also show up as pelvic or lower-abdominal discomfort.

Pelvic floor and musculoskeletal pain

Tight or overactive pelvic-floor muscles, and problems in the hips or lower back, can refer pain into the pelvis. This kind of pain is often worse with certain positions or activity rather than tied to the menstrual cycle.

Less common but serious causes

Uncommonly, pelvic pain reflects appendicitis, ovarian torsion, an ectopic pregnancy, or — rarely — a gynecologic cancer. New bleeding after menopause, persistent bloating with feeling full quickly, or unexplained weight loss alongside pain should always be checked promptly.

Where menopause and perimenopause fit

Hormone shifts in perimenopause can make periods heavier or more erratic and cramps more noticeable, and conditions like fibroids and endometriosis are common in the 40s. After menopause, though, new pelvic pain — and especially any bleeding — is less likely to be hormonal and should be evaluated. Pain and pressure can also overlap with bloating. To see where you are in the transition, read menopause stages.

Possible cause and typical clues — for discussion with a clinician, not self-diagnosis
Possible causeTypical clues
Period cramps (dysmenorrhea)Pain before and during periods, eases afterward; predictable timing
Ovulation painBrief one-sided twinge around mid-cycle
Ovarian cystDull ache, bloating or pressure; sudden severe pain if it ruptures or twists
Fibroids / adenomyosisHeavy periods, pelvic pressure, cramping
EndometriosisCyclical pain, pain with sex, bowel or bladder symptoms
UTIBurning on urination, needing to go often
PID (pelvic infection)Pain with discharge, fever, pain during sex
IBS / digestivePain linked to bowel habits, bloating, relief after a bowel movement
Pelvic floor / musculoskeletalWorse with position or activity, not tied to the cycle

Simple checks a clinician can do

A doctor will usually ask about your cycle, bowel and bladder habits, and sexual history, and may do a pelvic exam. High-yield first checks often include a pregnancy test, a urine test for infection, swabs for sexually transmitted infections, and a pelvic ultrasound. If heavy periods have left you drained, a clinician may check ferritin (iron stores) and, when symptoms fit, thyroid (TSH) — thyroid problems can worsen periods and fatigue. Heavy bleeding is a common cause of iron deficiency, and lingering tiredness has many possible causes worth exploring.

Pelvic pain has a wide range of explanations, and the same symptom can mean very different things from one woman to the next. Track when your pain happens and what eases or worsens it, and talk to your clinician — especially about any red-flag symptoms above — to get the right check for your situation.
