What counts as an irregular period?

A typical adult cycle runs about 21 to 35 days, with bleeding lasting up to about a week. Periods are considered irregular when the gap varies widely from month to month, when cycles are shorter than about 21 days or longer than 35, when periods stop for three months or more, or when bleeding is heavy, prolonged or occurs between periods or after sex. Some variation is normal in the first years after periods start and in the years before menopause.

Symptoms and when to see a doctor

  • No period for three months (or six months if previously irregular) and not pregnant
  • Bleeding between periods or after sex
  • Soaking through pads or tampons every hour or passing large clots
  • Cycles that suddenly change after being regular
  • Any bleeding after menopause

Seek urgent care for heavy bleeding with dizziness or fainting.

What happens at the clinic

  1. Cycle history: bring dates of your last several periods or a tracking app record.
  2. Pregnancy test: always checked first if pregnancy is possible.
  3. Pelvic ultrasound: looks for fibroids, polyps, PCOS features and lining thickness.
  4. Blood tests: commonly thyroid function, prolactin, reproductive hormones and a blood count for anemia.
  5. Treatment plan: the doctor explains the likely cause and options.

Treatment outlook

When stress, rapid weight change or intense exercise is the cause, cycles often return to normal as these settle. Cyclic progestin can trigger a regular bleed and protect the uterine lining. Combined oral contraceptives or a hormonal IUD can regulate or lighten periods. Underlying problems such as thyroid disease, high prolactin, polyps or fibroids are treated directly. For those trying to conceive, treatment focuses on restoring ovulation.

Risks and side effects

Long gaps without periods can let the uterine lining thicken, which raises the risk of abnormal cells over time, so persistent irregularity should not be ignored. Heavy bleeding can cause anemia. Hormonal medicines may cause spotting, breast tenderness or mood changes at first.

Choosing a clinic for irregular periods in Seomyeon

  • Choose a clinic that does ultrasound and blood tests on-site so the work-up can be done in one visit.
  • Ask whether hormone tests need to be timed to a specific cycle day.
  • If pregnancy is a goal, ask whether the doctor will plan treatment around ovulation.
  • Ask how the clinic follows up results and when to return.
  • Bring a list of medicines and supplements, including any herbal remedies.

Frequently asked questions

Is it normal for periods to be irregular sometimes?

Occasional variation is common, especially with stress, illness or travel. Repeated cycles outside about 21 to 35 days, missing periods for months or very heavy bleeding should be checked by a doctor.

What tests are done for irregular periods?

Typically a pregnancy test, transvaginal or abdominal ultrasound, and blood tests for thyroid function, prolactin, reproductive hormones and blood count. Further tests depend on the findings.

Can stress cause irregular periods?

Yes. Stress, poor sleep, rapid weight loss or gain and heavy exercise can disrupt the hormones that control ovulation, delaying or stopping periods. Other causes should still be ruled out.

Will birth control pills fix irregular periods?

The pill creates regular withdrawal bleeds and can reduce heavy bleeding, but it does not treat every underlying cause. A doctor should first check why cycles are irregular.

Can Korean medicine help irregular periods?

Some people combine Korean medicine with conventional care. It is sensible to have an OB-GYN rule out conditions such as PCOS, thyroid disease or fibroids first and to tell each practitioner about all treatments.
