Irregular Or Unscheduled Bleeding

Many women struggle with both the heaviness and the timing, of their bleeding. The ideal ’28 day cycle’ seems pretty elusive for some! There are a number of causes of irregular bleeding, and what investigations need to be done depend a bit on the age and fertility plans of the patient.


Possible causes

Common causes of irregular bleeding can include:

  • Ectropion: a fragile area on the cervix that can cause bleeding after sex or randomly.

  • Endometriosis: often linked to painful periods, painful sex, spotting, and fertility issues.

  • Infection: cervical or vaginal infections can cause bleeding, discharge, and pain.

  • Hormonal fluctuations: commonly related to contraception such as the pill, implants, or IUDs, causing “break-through” bleeding.

  • Ovarian cysts: some cysts can trigger irregular bleeding.

  • Perimenopause: hormonal changes leading up to menopause can cause unpredictable, heavy, or light bleeding.

  • PCOS: can cause infrequent, irregular, or heavy periods and affect ovulation.

  • Polyps: small growths in the uterus or cervix that may cause bleeding.

  • Pregnancy: early pregnancy should always be ruled out in anyone sexually active and still having periods.


What to do

With such a range of possibilities, it can be tricky to make a quick diagnosis. Often blood tests, swabs, and a scan will be needed to investigate the cause. Occasionally a biopsy from the lining of the womb, or a surgical procedure such as hysteroscopy, colposcopy, or laparoscopy will be necessary.
