Updated May 06, 2016. There are two menstrual cycle phases that occur during every monthly cycle. Each cycle begins on the first day you have your period and end on the day before you begin menstruating again. The first phase is the follicular phase, or the proliferative phase. The follicular phase begins on Day 1 of the menstrual cycle. Estrogen and progesterone levels are at their lowest during menstruation.
And about one year before their first period, many girls experience a marked growth spurt. A girl's first period is usually very light, with sometimes only spotting or very little blood. The typical menstrual cycle is 28 days long, but periods are often irregular during the first few years of menstruation. During this time, girls may skip menstrual cycles, or the cycles may occur multiple times in one month, or less frequently than expected.
