What are menstrual irregularities?

Your menstrual cycle is counted from the first day of your period to the first day of the next. Many women have menstrual cycles that last between 21 and 35 days. The length of period bleeds also vary from 2 – 7 days. Menstrual cycles become less regular as you near menopause.

You should have regular periods unless you are:

  • Pregnant or breastfeeding
  • Postmenopausal
  • Have a medical condition that causes your periods to stop.


It is thought that up to a quarter of women experience irregular menstrual cycles. This means they may have:

  • Heavy periods (menorrhagia) is when you have excessive bleeding during your period.
  • Bleeding or spotting between periods (intermenstrual bleeding)
  • Infrequent periods (oligomenorrhea) – periods that occur more than 35 days apart.
  • Irregular periods when your cycles vary from period to period, typically with a variation of more than 20 days difference.
  • Delays the return of menstruation.

What are heavy periods?

  • Bleeding through one or more pads or tampons every 1-2 hours
  • Signs of anemia (low iron) – dizziness, lightheadedness, weakness, tiredness, chest pain or trouble breathing
  • You have menstrual blood costs larger than a 20c piece (smaller clots are normal to pass)

  • Blood tests
  • Pregnancy test

Your heavy bleeding may be treated with hormonal birth control or medication to lessen the bleeding. If you also have strong pain you may be prescribed pain medication. In rare cases you may require surgery to treat the cause of the bleeding.

What treatment would I be offered?

There are different treatment options that could be recommended. This depends on your age, desire to have children in the future, severity of bleeding, and the cause of heavy periods. The different options of treatment could be:

  • Hormonal tablets
  • Mirena IUD
  • Endometrial ablation (destroying the lining of the uterus)
  • Hysterectomy

What is intermenstrual bleeding?

Unusual or abnormal bleeding is any bleeding that happens when you do not have your period, including:

  • Spotting or bleeding at any time during your menstrual cycle other than your period
  • Bleeding after sex, more than once

  • Midcycle bleeding can occur at the time of ovulation
  • Infections like chlamydia

  • Cervical or endometrial polyp
  • Cancer of the cervix or lining of the uterus
  • Anticoagulant medications

What should I do if I have intermenstrual bleeding?

Your doctor will check for causes of irregular bleeding. Many of these are easy to treat and do not indicate a serious underlying problem. Hormonal birth control may be prescribed.

What are infrequent periods?

Infrequent periods are periods that occur at different times with long lengths between them. If you are missing periods for three months in a row, or have not had your first period by 15, this is called amenorrhea. You may have a hormonal imbalance (not enough oestrogen). This can have serious health effects.

What causes infrequent periods?

Infrequent periods may be caused by:

  • Stress
  • Eating disorders, especially anorexia nervosa
  • Gaining or losing too much weight
  • Hormonal problems such as PCOS
  • Pregnancy and breastfeeding
  • Serious health problems like tumors in the brain

Your periods should start again once these problems are treated.

What are irregular periods?

If your cycle is shorter or longer than average you are considered to have irregular periods. That is:

  • If your next period is less than 24 days from the start of your last period
  • If your next period is more than 38 days from the start of your last period
  • Your cycle length varies by more than 20 days from month to month

What causes irregular periods?

Irregular periods are normal for teenage girls and tend to become more regular after a few years. Perimenopausal women (women nearing and entering menopause) have periods that become more irregular over time until they eventually stop.
Irregular periods can be caused by:

  • Eating disorders
  • Thyroid problems (hyperthyroidism or overactive thyroid)
  • High level of prolactin in the blood
  • Primary ovarian insufficiency (POI) when the ovaries stop working normally before 40. This is not early menopause as you may still have periods and can get pregnant
  • Certain medications (e.g. anxiety or anti-epileptic drugs)
  • PCOS
  • Pelvic inflammatory disease (PID)
  • Stress
  • Uncontrolled diabetes (both Type 1 and Type 2)
  • Obesity
