Menstruation: This phase involves the shedding of the uterine lining, resulting in menstrual bleeding. It typically lasts 3 to 7 days and marks the start of the menstrual cycle
2. Follicular phase: Lasting about 13 to 14 days, this phase starts with menstruation. Hormones spur follicle growth in the ovaries, housing immature eggs. Rising estrogen levels thicken the uterine lining for pregnancy readiness.
3. Ovulation: Occurring around the cycle's midpoint, ovulation sees the release of a mature egg from an ovary. It is often accompanied by changes in cervical mucus or mild abdominal discomfort.
4. Luteal phase: The uterus prepares for pregnancy. If fertilization does not occur, the cycle restarts.
