Bleeding Mid-Cycle During Perimenopause

During perimenopause, ovulation becomes less predictable and hormone levels fluctuate. The uterine lining may therefore build up and shed at unexpected times, causing spotting between periods, shorter or longer cycles, missed periods, or a heavier flow. Perimenopause can present with irregular bleeding, but it is not the only possible explanation. Pregnancy-related bleeding, fibroids, polyps, infection, thyroid problems, medicines, and changes in the cervix or uterine lining can also alter bleeding. A clinician can decide which possibilities fit your age, symptoms, medical history, and pregnancy risk.

Record when bleeding starts and stops, whether it is spotting or a full flow, and whether you pass clots. Note pelvic pain, bleeding after sex, unusual discharge, missed periods, hot flushes, and any new medicine or hormone treatment. Take a pregnancy test if pregnancy is possible, even when cycles have become irregular. Arrange a routine medical appointment for a new pattern, bleeding that keeps returning, or any change that concerns you. Assessment may include a pregnancy test, examination, blood tests, cervical screening if due, or imaging, depending on your circumstances.

Seek urgent medical care if bleeding is very heavy, you feel faint or weak, you have severe or worsening pelvic pain, or you may be pregnant and develop bleeding with one-sided pain, shoulder-tip pain, dizziness, or collapse. Prompt assessment is also appropriate for fever with pelvic pain or foul-smelling discharge. Bleeding after menopause, meaning after periods have stopped completely for a sustained interval, should always be medically assessed rather than assumed to be part of perimenopause.

Ask whether your bleeding pattern fits the menopause transition, whether pregnancy or anaemia testing is appropriate, and whether your examination or history suggests an ultrasound or another test. You can also ask which changes should bring you back sooner and whether any current medicine could be contributing. Bring your bleeding record and the dates of your latest cervical screening and last normal period if you know them.
