Does menstruation belong to luteal phase

The menstrual period is the follicular phase, not the luteal phase. The luteal phase refers to the formation of the corpus luteum after ovulation and is called the luteal phase until the next menstrual period. During the luteal phase, vaginal secretions gradually thicken and increase before menstruation, mainly due to the strong secretion of endometrial glands. In addition, in the luteal phase due to the formation of corpus luteum, basal body temperature will show increased phenomenon, such as general ovulation after the body temperature will reach 37℃, and this high temperature state to last at least 12 days, clinically can explain luteal secretion normal. Therefore, menstrual period is not luteal phase.
