Up until these stages, women experience years of fluctuating PMS hormones each and every month, causing pre-menstrual symptoms (PMS). These fluctuating hormones regulate the menstrual cycle and subsequently cause undesirable side effects. The main hormones before period onset include estrogen and progesterone. In a basic menstrual cycle, estrogen rises for about two weeks then begins to fall, at which point progesterone begins to rise for about two weeks then falls again. This up and down continues each month.
A menstrual cycle is the time period between your first day of your menstrual period, the time you bleed, until the next time of your menstrual period. The changes associated with ovulation and menstrual cycle are brought on by fluctuations in hormones at different times of the month. The luteal phase (days 14 through 28) is the time from when the egg is released (ovulation) until the first day of menstruation, when you get your period. 2  It is a structure that grows in the ovary where a mature egg was released at ovulation.
