Best Answer: Hi, You mean monthly period of girls. Monthly period is called Menstruation. Mestruation is a normal part of a womanâs reproductive cycle. The ovary periodically releases an egg. It also releases a hormone called oestrogen, which stimulates the lining of the uterus to grow and get prepared to receive the fertilized egg. If, however, the egg does not get fertilized, the uterus sheds its lining resulting in menstrual flow. This flow repeats itself in a cycle of approximately 28 days until a woman gets pregnant or has approached menopause.
