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 step is getting to know your body and understanding what is happening during your menstrual cycle: Your period is usually on a cycle of 28 days, though different women's cycles vary by a few days. The day you start bleeding is considered the first day of your cycle, meaning that 28 days or so from then you will bleed again and then your cycle will start all over. In other words, from the first day of one period until the first day of the next is your menstrual cycle.
