Premenopause (usually up to the late 30s/early 40s)
Premenopause refers to the years between puberty and the first signs of menopausal change. During this time, reproductive hormones like oestrogen and progesterone fluctuate in a regular cycle, allowing for ovulation and menstruation.² Most people in this stage can conceive naturally and experience symptoms like PMS (premenstrual syndrome), including cramps, mood swings, breast tenderness, and fatigue.²
This stage is considered hormonally ‘normal’, but some may experience irregular periods, fertility difficulties, or medical conditions that bring on early menopause. For most, though, hormonal changes only begin to shift in the next stage.
