What an irregular monthly period can mean

A period can become early, late, lighter, heavier, shorter, longer, or absent. Anovulation is one reason the expected monthly pattern can disappear. Polycystic Ovary Syndrome may cause irregular ovulation, while Perimenopause can make timing and flow change during a hormonal transition. Premature Ovarian Insufficiency is another possible cause of infrequent periods. Pregnancy, breastfeeding, thyroid problems, medicines, major stress, and changes in exercise or weight should also be considered. The symptom alone does not identify one cause.

Write down period dates, flow, spotting, cramps, new symptoms, medicines, contraception, and pregnancy possibility. Take the record to a clinician if the change repeats or concerns you. A pregnancy test is appropriate when pregnancy is possible. Your clinician may discuss examination, blood tests, or treatment according to the findings. If predictable bleeding or contraception is important, the Combined Pill may be an option after checking whether it suits your medical history. Metformin for PCOS may be discussed when PCOS is part of the assessment.

Arrange an appointment for repeated missed periods, bleeding between periods, bleeding after sex, new pelvic pain, or troublesome symptoms such as hot flushes or excess hair growth. Seek urgent help for severe pain, faintness, or heavy bleeding with weakness, especially if pregnancy is possible. These red flags guide urgency more than the regularity of the calendar.

Ask which explanations fit your history, whether you need a pregnancy check or other tests, and how your treatment choices relate to contraception, symptoms, and plans for pregnancy.
