Painful Periods: When It's Normal and When to See a Doctor

Period pain (dysmenorrhea) affects about half of all women at some point. Mild to moderate cramping during the first one or two days of a period — that responds to a painkiller and a hot water bottle — is normal. Pain that stops you from going to school, work, or that wakes you up at night is not.

What's considered normal

• Mild to moderate cramping for 1–2 days.
• Pain centred in the lower abdomen, sometimes radiating to the lower back.
• Pain that improves with paracetamol, ibuprofen, or a hot water bottle.
• Pain that doesn't stop you from doing your usual activities.

Signs the pain is NOT normal

• Severe pain that doesn't respond to standard painkillers.
• Pain that lasts longer than 2–3 days.
• Pain outside your period (in between periods, with intercourse, with bowel movements).
• Pain that gets worse year by year.
• Pain accompanied by very heavy bleeding, large clots, or bleeding longer than 7 days.
• Pain with infertility, painful urination or rectal pain.

Common conditions behind severe period pain

Endometriosis

Tissue similar to the uterine lining grows outside the uterus — on ovaries, fallopian tubes or pelvic walls. Pain typically worsens over the years and may cause infertility. Diagnosis usually requires ultrasound and sometimes laparoscopy.

Adenomyosis

Uterine lining grows into the muscle of the uterus, causing heavy, painful periods. More common in women in their 30s and 40s.

Fibroids

Benign growths in the uterus. Depending on size and location, fibroids can cause heavy bleeding, pelvic pressure and severe cramping.

Pelvic inflammatory disease (PID)

Infection of the upper genital tract, usually from untreated STIs. Causes pain that doesn't follow the menstrual cycle pattern. Needs prompt antibiotic treatment.

Ovarian cysts

Most ovarian cysts are harmless and resolve on their own. Large or complex cysts can cause pain and need monitoring.

What you can do at home

• Heat — hot water bottle or warm shower for 15–20 minutes.
• Paracetamol 500 mg or ibuprofen 400 mg every 6–8 hours during pain (with food).
• Light exercise — yoga, walking, gentle stretching.
• Track your symptoms in a period app — share patterns with your doctor.
• Cut down on caffeine and processed sugar in the week before periods.

When to see a gynaecologist

• Pain getting worse over time.
• Painkillers no longer work.
• Period interfering with school, work or sleep.
• Heavy bleeding (changing pad/tampon every 1–2 hours).
• Trying to conceive without success.
• Pain anywhere outside the period itself.

A gynaecological consultation typically includes a detailed history, an examination, and a pelvic ultrasound. Most causes of severe period pain are treatable — once we know what's behind it.
