Perimenopause and your period

As ovulation becomes less predictable, a cycle may be shorter or longer, and bleeding may be lighter, heavier or different from your usual pattern. A period can be missed and then followed by heavier bleeding. These changes may occur with [Hot Flushes](/symptoms/hot-flushes/), sleep disruption or mood changes. However, a period change is not automatically caused by perimenopause: pregnancy, fibroids, thyroid problems, medicines and other conditions can also affect bleeding.

Record the first and last day of bleeding, how often you change period products, clots, pain and any missed cycles. Keep supplies available when timing is unpredictable. Rest, fluids and heat may ease discomfort, while a pharmacist can discuss suitable pain relief after checking your health history. If pregnancy is possible, use contraception and take a pregnancy test when appropriate; ovulation can still occur during perimenopause.

Book an appointment for a persistent change, bleeding between periods, bleeding after sex, new pelvic pain or symptoms of anaemia such as unusual tiredness, breathlessness or dizziness. Seek urgent care if bleeding is very heavy with faintness, severe weakness, chest discomfort or trouble breathing. After menopause, any vaginal bleeding should be assessed promptly.

Ask what may explain your pattern, whether you need a pregnancy test or examination, and which options could reduce troublesome bleeding. Bring your tracking notes and list any hormones, blood thinners or other medicines.
