On average, perimenopause typically lasts up to 10 years^[1], but it can vary between women. For some women, perimenopause might last only a few months, while for others, it can extend for more than a decade.

Perimenopause ends when you’ve gone 12 consecutive months without a menstrual period, marking the onset of menopause.

The best way to test for perimenopause is to identify your symptoms and have your blood tested. Our ground-breaking MyFORM® Perimenopause test is the only at-home blood test in the UK that can accurately screen for perimenopause, by measuring key hormones on day 14 and 21 of your menstrual cycle.

Forth offers a range of tests for perimenopause, with MyFORM® providing a detailed report into the behaviour of your female hormones during the menstrual cycle. This test can identify when a woman’s hormones are typical of perimenopause and provides actions that can be taken to best manage this transitional phase.

Perimenopause and menopause are different stages of the menopause.

• Perimenopause – a natural transitional phase that leads up to menopause, periods are likely to become less regular and you can experience a range of symptoms. During this phase, oestrogen levels will steadily decline.
• Menopause – this phase is denoted by the end of ovulation, usually defined by more than 12 months since the last period. Oestrogen levels will remain at their lowest levels. The majority of “menopause symptoms” actually refer to those experienced in perimenopause.

It is recommended that you start HRT as soon as you experience symptoms related to perimenopause. Studies have shown that starting HRT earlier in the transition to menopause can reduce the risk of long-term conditions such as: osteoporosis, coronary heart disease, and cardiovascular disease.
