What is the time when physical changes occur on the body during a menstruation cycle?

Physical changes during the menstrual cycle primarily occur in response to hormonal fluctuations, with the most noticeable changes occurring in the luteal phase and menstruation itself. After ovulation, the body prepares for a potential pregnancy, leading to changes such as breast tenderness and bloating due to increased progesterone. If pregnancy does not occur, hormone levels drop, triggering menstruation, which can involve cramping and the shedding of the uterine lining. Overall, these changes typically happen over the course of about 28 days, with menstruation lasting around 3 to 7 days.
