The period of fertility is quite long for a woman: with puberty, which begins on average at 13 years and menopause, which occurs around 51 years, it still represents 38 years and nearly 500 rounds of 28 days!
Starting the first day of your period and ending the first day of the next menstrual period, a cycle lasts an average of 28 days, but there are wide variations from one woman to another and for the same woman.
Regular cycles have a dependence of the good functioning ovarian, itself controlled by two small glands of the brain (the hypothalamus and pituitary), it takes little to disrupt the mechanism precision: most of the conditions endocrine, being anorexic, or obese and to a lesser extent, stress can affect the smooth running of the menstrual cycle. This explains why it happens to all women or almost, to have shorter cycles and other longer during their lives. At the time of puberty and before menopause, this irregularity is almost inevitable.
