Menstrual cycle hormone graph

That depends on the individual! Different women have a different cycle. Some women are regular and they have no problems with periods, whereas many women are suffering from abnormal periods. This is mainly due to the life style and lack of nutrition from the food. Over a period of 28 days the menstrual cycle goes through three different phases. These phases are known as follifuclar, luteal and ovulation. Variations in the cycle may occur due to diseases and other health problems as well. Sometimes healthy women may have an early period due to fright or panic. This is rare but it is not unheard of.
