Since the beginning of life on planet earth, among males and females only the females are endowed with the gift of producing new life. But for this huge privilege a woman has to pay the price almost half of her life, puberty to menopause by going through Menstrual Cycle. Menstruation is a natural phenomenon indicating a woman’s fertility. Having regular menstrual cycles is a sign that important parts of the female body are working normally. It also prepares the body for pregnancy each month. A cycle is counted from the first day of the first period to the first day of the next period. But problem with Menstruation begins when abnormality in the regular cycle occurs. The normal range of age for the onset of periods is 9–17 years. Most girls begin puberty at around 10 years of age with an initial phase of accelerated growth and breast development known as breast budding. Shortly after, pubic hair appears, and by 12 years more than 50 per cent of young girls have underarm hair.
