Frequent irregular periods: what to know

Irregular periods may come earlier or later than expected, vary in flow, or appear as spotting between fuller bleeds. Anovulation means an egg is not released in a cycle and can lead to unpredictable bleeding. Perimenopause commonly changes cycle timing. Polycystic ovary syndrome may disturb ovulation, while premature ovarian insufficiency can cause irregular or absent periods earlier than expected. Pregnancy, breastfeeding, major stress, changes in weight or exercise, thyroid problems, and hormonal contraception are other possibilities. The pattern is useful information, but it does not identify a single cause by itself.

Keep a cycle record showing bleeding dates, flow, pain, discharge, pregnancy possibility, contraception, medicines, and symptoms such as acne or increased facial hair. Arrange a clinical review if the pattern persists, changes suddenly, or affects your wellbeing. Assessment may include a pregnancy test, blood tests, and an examination or scan guided by your history. The combined pill or metformin for PCOS may be considered in selected situations, but treatment should match your health and pregnancy plans.

Seek urgent help for heavy bleeding with dizziness or fainting, severe pelvic pain, a positive pregnancy test with bleeding, or sudden severe illness. Arrange an earlier review for bleeding after sex, persistent bleeding between periods, new symptoms of anaemia, or periods stopping unexpectedly. The warning features determine urgency; an irregular cycle alone does not prove a serious condition.

Could I be ovulating irregularly? Should pregnancy, thyroid function, or hormone changes be checked? Do my symptoms fit PCOS or perimenopause? Which treatment would protect my health and fit my pregnancy plans? When should I return if the pattern continues?
