A period that arrives a few days early or late is not always a reason to worry. Menstrual cycles can naturally vary at different stages of life. But when periods become consistently unpredictable, unusually frequent, widely spaced or absent for months, it may be time to look beyond the calendar.
Irregular periods are common, but they should not simply be ignored—especially when the pattern changes or other symptoms appear.
A typical menstrual cycle often occurs every 21 to 35 days, although menstrual patterns can vary. In adults, bleeding may be considered abnormal when cycles are consistently shorter than 21 days, longer than 35 days, or vary significantly from one cycle to another. Bleeding between periods, unusually heavy bleeding and prolonged periods may also require evaluation.
Irregular menstruation may involve:
· Periods that come too frequently or too far apart
· Unpredictable cycle timing
· Missed periods
· Bleeding between periods
· Periods lasting longer than usual
· Unusually heavy or light bleeding
A changing menstrual pattern does not automatically mean something is seriously wrong. However, persistent changes deserve attention.
There is no single answer to “what is the reason for irregular periods?”
Menstrual cycles are influenced by a complex interaction between the brain, hormones, ovaries and uterus. Changes in ovulation, hormone levels, physical health and certain uterine conditions can all affect the timing or pattern of bleeding.
Some of the common causes of irregular period patterns include:
If ovulation does not occur regularly, menstrual cycles may become unpredictable or widely spaced. Ovulatory dysfunction can occur in conditions such as polycystic ovary syndrome (PCOS) and thyroid disorders.
Periods can be naturally less predictable during the first few years after menstruation begins. Menstrual patterns may also change during the transition to menopause, known as perimenopause.
Conditions such as uterine fibroids, polyps and adenomyosis can contribute to abnormal or heavy menstrual bleeding.
Problems with blood clotting, certain medicines and other medical conditions can also contribute to abnormal uterine bleeding. The internationally recognised FIGO PALM-COEIN system helps clinicians classify potential structural and non-structural causes of abnormal uterine bleeding.

The timing of your period is only one part of the picture. Other irregular periods symptoms may include:
· Very heavy bleeding
· Bleeding or spotting between periods
· Periods lasting more than seven days
· Pelvic pain or pressure
· Worsening menstrual pain
· Missed periods for several months
Tracking your menstrual cycle, including the dates, duration and approximate heaviness of bleeding, can help your doctor understand the pattern more clearly.
You should consider consulting a gynaecologist if your periods have become consistently irregular, if you are missing periods for several months, or if your usual menstrual pattern has changed significantly.
Medical advice is particularly important if you experience:
· Bleeding between periods
· Bleeding after sexual intercourse
· Very heavy menstrual bleeding
· Periods lasting longer than seven days
· Persistent pelvic pain
· A sudden or unexplained change in your usual cycle
Bleeding after menopause should always be medically evaluated.
Heavy bleeding may occasionally require urgent medical attention. According to ACOG, if you are soaking through a pad or tampon every hour for more than two consecutive hours and also experience symptoms such as dizziness, light-headedness, chest pain or shortness of breath, seek emergency medical care.
Your gynaecologist will usually begin by discussing your menstrual history, symptoms, medicines and overall health.
Depending on your individual situation, the evaluation may include:
· A physical examination
· Pregnancy testing, when relevant
· Blood tests
· Assessment for hormonal or other medical conditions
· Ultrasound or other imaging, when indicated
The purpose is not simply to “regularise” the period. It is to understand why the menstrual pattern has changed and identify the most appropriate next step.

Irregular periods are not always a sign of a serious condition. Life stages such as adolescence and perimenopause can naturally bring changes to the menstrual cycle.
But persistent irregular menstruation, unusually heavy bleeding, bleeding between periods or a significant change in your normal pattern should not be dismissed.
If you are searching for a good gynaecologist near me, choose a qualified specialist who can assess your complete menstrual and medical history—not just one symptom or one test result.
Your menstrual cycle is not merely a monthly inconvenience. Sometimes, it can also offer useful information about your overall reproductive and hormonal health.
