Perimenopause, the transitional phase before menopause, brings about a multitude of changes in a woman's body, with one of the most noticeable being the impact on menstrual cycles. Our latest consumer survey of over 1,500 women going through all stages of menopause revealed that 60% of women going through perimenopause experience more intense PMS symptoms.

Understanding how perimenopause affects your periods is essential for recognising the signs of entering this significant life stage. Here we explain 'perimenopausal periods', how they're different to normal periods, addressing common concerns and how to manage these changes.

What to expect during perimenopause

There are a number of common changes in periods you can expect during perimenopause:

Irregular or skipped periods: Hormonal fluctuations can result in irregular menstrual cycles or skipped periods. Discover the signs of hormonal imbalances.
Changes in flow: Perimenopausal periods may bring alterations in the volume of menstrual flow, with women experiencing heavier or lighter bleeding.
Spotting: Spotting between periods is common and is linked to hormonal imbalances during perimenopause.
Increased or more intense PMS symptoms: Hormonal changes can intensify premenstrual symptoms, leading to mood swings, cramps, breast tenderness, and irritability.
Menopause symptoms: Perimenopause can also bring symptoms like brain fog, hot flashes, night sweats and changes in sleep patterns. Learn more in 'Common signs of perimenopause' and 'How do you know you're starting perimenopause?'.

Are perimenopause periods worse than normal periods?

During perimenopause, many women experience changes in their menstrual cycles that may differ from what they consider 'normal'. These changes include heavier or lighter flow, longer or shorter durations and severe cramping. The fluctuations are primarily attributed to hormonal shifts, specifically a decline in oestrogen and progesterone production. As hormonal balance is disrupted, the uterine lining may be thicker, leading to heavier periods and more intense cramping.

Can I get periods every 2 weeks during perimenopause?

Yes, irregularities in the menstrual cycle are typical during perimenopause and some women may experience periods every two weeks. The unpredictable hormonal fluctuations can lead to shortened cycles, longer cycles or even irregular patterns. It's crucial to track these changes to understand your unique perimenopausal journey.

What is a flash period in perimenopause?

A 'flash period' refers to a situation where, after missing several months of periods, a woman suddenly experiences one. This irregularity is a common occurrence during perimenopause and is often associated with hormonal fluctuations.

What is the last period like in perimenopause?

The last period, often referred to as the menopause transition, can vary from woman to woman. Some may experience a heavier flow, while others may have a lighter period. It is an individual experience and there is no one-size-fits-all scenario.

Can I still get pregnant during perimenopause?

Yes, it's important to note that pregnancy is still possible during perimenopause, even if periods are irregular. It's crucial to use contraception if you wish to avoid unintended pregnancies. You may be interested in reading 'Nutritionist advice for a healthy pregnancy'.

When should I see a doctor?

If you experience unusually heavy bleeding (defined as soaking through one tampon or pad an hour for several hours), prolonged periods lasting more than seven days or if you're concerned about changes in your menstrual cycle, it's advisable to consult with a healthcare professional.
