During a normal menstrual cycle, the levels of the hormones estrogen and progesterone increase and decrease in a regular pattern. Ovulation occurs in the middle of the cycle, and menstruation occurs about 2 weeks later.During perimenopause, hormone levels may not follow this regular pattern.enopause is defined as the absence of menstrual periods for 1 year. The average age of menopause is 51 years, but the normal range is 45 years to 55 years. The years leading up to this point are called perimenopause.
It occurs in approximately monthly cycles throughout a woman's reproductive life, except during pregnancy. Menstruation starts during puberty (at menarche) and stops permanently at menopause (see Menopause). By definition, the menstrual cycle begins with the first day of bleeding, which is counted as day 1. The cycle ends just before the next menstrual period. Menstrual cycles normally range from about 25 to 36 days. Only 10 to 15% of women have cycles that are exactly 28 days. Also, in at least 20% of women, cycles are irregular.
