THE MENSTRUAL CYCLE is a pattern of physiological changes that occurs in fertile females. The menstrual cycle is controlled by the endocrine system. This is why detecting a change in your ovulation cycle may indicate an endocrine problem.

The menstrual cycle is divided into three distinct phases:

  • Menstruation
  • The Follicular Phase
  • The Luteal Phase

The length of each phase of the menstrual cycle varies from woman to woman and cycle to cycle. The average length of time between cycles is about 28 days. Menstrual cycles longer or shorter than 28 days does not mean there is a problem.

There are many things that can have an effect on the length and regularity of your menstrual cycle. It is very common that women today don't have a menstrual cycle every 28 days. Many women only have one menstrual cycle every 45 days and this is referred to as an irregular menstrual cycle. For women who experience irregular menstrual cycles it is difficult to know the best time to conceive, and your saliva is the best adviser in such a case.
