2. Longer Menstrual Cycles
In the later stages of the menopausal transition, the ovaries become more resistant to a hormonal stimulus which, in conjunction with the rising FSH levels as well as a drop in Estradiol, results in menstrual delays and missed periods.
Curiously enough, women experiencing a lengthening of their menstrual cycles often report having significantly heavier flow when menstruation does occur.
Menstrual periods will eventually cease altogether. Once a full 12 months have passed since a woman’s last period, menopause will have concluded.
