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.
The first day of menstrual bleeding is the date used for the last menstrual period (LMP). The typical length of time between the first day of one period and the first day of the next is 21 to 45 days in young women and 21 to 31 days in adults (an average of 28 days).
