The uterine cycle does not continue during pregnancy because during pregnancy the uterus is occupied by the developing fetus and the placenta. The uterine cycle is the monthly series of events that occur in the uterus in response to hormonal changes, and it is divided into three phases: the menstrual phase, the proliferative phase, and the secretory phase. Menarche refers to the first occurrence of menstruation, and the cycle is ultimately controlled by the hypothalamic-pituitary-gonadal axis, which involves the release of GnRH, FSH, and LH. Painful myometrial contractions may occur during menstruation due to the shedding of the endometrial lining.
