What should you know about super irregular periods?

Irregular periods may mean cycles arrive unusually close together, far apart, vary greatly in length, or stop for a time. [Anovulation](/conditions/anovulation/) means an egg is not released, which can make bleeding unpredictable. [Polycystic Ovary Syndrome](/conditions/polycystic-ovary-syndrome/) may affect ovulation, while [Perimenopause](/conditions/perimenopause/) can change cycle timing and flow. [Premature Ovarian Insufficiency](/conditions/premature-ovarian-insufficiency/) is another possible cause of absent or irregular periods, particularly with hot flushes or fertility changes.

Stress, major changes in exercise or weight, illness, thyroid problems, medicines, and pregnancy can also alter a cycle. Irregular bleeding is a symptom and does not by itself identify one condition.

Track the first day of each bleed, its duration, flow, pain, spotting, medicines, and pregnancy possibility. Arrange an appointment if the pattern persists, periods stop unexpectedly, or bleeding is troublesome. A clinician may discuss pregnancy testing, blood tests, or an ultrasound. Depending on the cause and your goals, options can include the [Combined Pill](/treatments/contraception-and-family-planning/combined-pill/) or [Metformin for PCOS](/treatments/medical-gynaecology/metformin-for-pcos/), but treatment should follow assessment.

Seek urgent help for heavy bleeding with faintness, severe pelvic pain, shoulder-tip pain, or weakness, especially if pregnancy is possible. Arrange prompt review for bleeding after sex, bleeding between periods that keeps recurring, or a missed period with pain. These warning signs need assessment because the symptom pattern, not its frequency, determines urgency.

Ask what pattern your cycle suggests, whether pregnancy or hormone testing is appropriate, how treatment may affect fertility, and which changes should lead you to seek earlier review.
