Menstrual Cycle Monophasic

The menstrual cycle is a natural process in a woman’s body that occurs monthly and is associated with changes in hormonal levels. Normally, the menstrual cycle lasts from 21 to 35 days and can vary depending on various factors such as stress, nutrition, physical activity and others. In order to understand how the menstrual cycle works, it is necessary to consider its main stages.

The first stage is the follicular phase, which begins on the first day of menstruation and continues until ovulation. At this stage, the body begins to prepare for conception. A follicle is a structure in the ovaries that contains an egg and produces estrogen. During this stage, estrogen levels increase significantly, which can lead to breast engorgement, swelling, and weight gain.

The second stage is the ovulatory phase. It begins immediately after estrogen levels rise. Estrogen levels drop sharply and ovulation occurs during this phase.
