Is the third day of menstruation generally part of the luteal phase or another phase?

Day 3 of menstruation falls within the follicular phase. The female menstrual cycle is divided into three phases: the follicular phase, the ovulatory phase, and the luteal phase. - The follicular phase spans from the onset of menstruation until ovulation. - The ovulatory phase encompasses the five days preceding ovulation and the four days following it. - The luteal phase typically occurs from day 15 to day 28 of the menstrual cycle—approximately 14 days—and during this phase, the ovaries are influenced by progesterone (secreted by the corpus luteum), promoting the maturation of follicles and establishing the physiological conditions necessary for fertilization.
