Menstruation

• Hi my name is sudarshanshrestha and now I am talking about menstruation . Menstruation is a monthly shedding of female's uteral lining; it lasts about 3 to 5 days (average) and contains blood and tissue that exits her body through the cervix and vagina – the first day of menstruation is the first day of your period.The menstrual cycle is the recurrent approximately monthly .The menstrual cycle is the hormonal driven cycle; day 1 is the first day of your period (bleeding) while day 14 is the approximate day you ovulate and if an egg is not fertilized, hormone levels eventually drop and at about day 25; the egg begins to dissolve and the cycle begins again with the period at about day 30.Most periods vary somewhat, the flow may be light, moderate or heavy and can vary in length from about 2 to 7 days; with age, the cycle usually shortens and becomes more regular.Problems with periods include the following: amenorrhea (no period), dysmenorrhea (painful period), and abnormal bleeding.The average age for a girl to get her first period in the US is 12, but the range of age is about 8 to 15 years old.Women usually have periods until about ages 45 to 55.
