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.
The symptom of hot-flashes are 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. Hot-flashes are associated with lower than normal estrogen production. Often, menstrual phases are synchronized with the Moon's phases, but it is not always so. Menstruation usually starts around New Moon. See the links under resources for more. Menstruation usually starts around New Moon. Proliferative phase begins once menstruation stops. Sometimes, menstruation can stop for a day, then resume. This phase is when estrogen levels gradually start to rise. When estrogen levels are low, there is an absence of cervical mucus. Signs of ovulation include a feeling of ovarian itching, increased cervical mucus that is egg white, increased mucus, increased body temperature and swollen genitals. The occurance of a Full Moon is a less reliable association with Ovulation. During secretory phase, progesterone produced by the corpus luteum in comparison to lower estrogen raises body temperature. Temperature for secretory phase ranges between 36.5℃ to 37℃. If body temperature is higher than 37℃ (98.6℉), or if you have hot-flashes, see estrogen deficiency. Premenstrual syndrome symptoms are likely from a sudden decrease in progestogen synthesis. Here, body temperature lowers under 36.5℃. Blog updates: breast topics and health related content.Symptoms
