This is the transitional phase before menopause when a woman's hormone levels begin to decline. Perimenopause can last for several years and is often associated with irregular periods and the onset of menopausal symptoms.
During menopause, a woman's ovaries cease releasing eggs, leading to a decline in hormone levels, notably estrogen and progesterone. This transition marks a significant life stage with unique physical and emotional changes.
This is the phase after menopause, which starts after 12 months without a menstrual period.
