The uterine cycle is divided into three phases: the menstrual phase (menses), the proliferative phase, and the secretory phase, in that order. The cycle starts with the menstrual phase, followed by the proliferative phase as the endometrium rebuilds, and ends with the secretory phase, preparing for potential implantation of an embryo.
