Answer 2

Answer:

The first period usually begins between twelve and fifteen years of age, a point in time known as menarche.[6] In the case of precocious puberty, they may occasionally start as early as eight; however, this onset may still be normal.[3] The average age of the first period is generally later in the developing world and earlier in developed world. The typical length of time between the first day of one period and the first day of the next is 21 to 35 days in adults (an average of 28 days[3][7][8]). Menstruation stops occurring after menopause which usually occurs between 45 and 55 years of age.[9] Bleeding usually lasts around 3 to 7 days.[3]
