Menstrual Phases
The menstrual cycle will be divided into 5 phases to simplify timing: menstruation, proliferative, ovulation, secretory and premenstrual.
Follicular phase has been divided up into menstruation and proliferative phases. Menstruation is when the uterus lining is shed. The proliferative phase is from the end of menstruation until ovulation: this is the time when the uterus rebuilds to prepare for potential pregnancy.
Luteal phase has been divided into secretory and premenstrual phases. The corpus luteum which produces progesterone is present during the secretory phase. Premenstrual phase begins after the corpus luteum disintegrates, and it ends at the beginning of menstruation.
Often, menstrual phases are synchronized with the Moon's phases, but it is not always so. Ovulation is commonly associated with a Full Moon, and menstruation usually starts around New Moon. Cervical mucus is a better indicator of ovulation. During secretory phase, progesterone can raise body temperature. See the links under resources for more. The symptom of hot-flashes is possibly associated with abnormally high body temperature. An excessive imbalance of progesterone or prolactin should be avoided. Decreased fertility may underlie symptoms indicating increased progesterone or prolactin. Premenstrual syndrome symptoms are likely from a sudden decrease in progestogen synthesis.Determining Menstrual Phase
