Fertilization, Ovulation and Menstruation .
Menstruation is a woman's monthly normal vaginal bleeding, often called the period.
There isn't one right age for a girl to get her period.
Most girls get their first period about two years after their breasts start to develop, when they're between age 10 and 15.
And it will continue till about age 51, usually lasting from three to eight days.
The menstrual cycle includes several phases. The first phase of the menstrual cycle begins on the first day of bleeding and lasts for about 14 days.
In a normal menstrual cycle, the brain makes the hormone GNRH, which travels in the blood to the pituitary gland.
The pituitary gland then releases two hormones, follicle -stimulating hormone, (F.S.H.), and luteinizing hormone, (L.H) which travel in the bloodstream to the ovary.
