LaoAt the end of a menstrual cycle, the unfertilized egg is either absorbed by the body or expelled during menstruation. The lining of the uterus, which thickened in preparation for a possible pregnancy, sheds as menstrual bleeding. This marks the start of a new menstrual cycle.

What event marks the end of one menstrual cycle and the beginning of another?
The shedding of the uterine lining, known as menstruation, marks the end of one menstrual cycle and the beginning of a new one.
When does menstrual flow takes place?
Menstrual flow typically occurs during the menstrual phase of the menstrual cycle, which is when a woman sheds the lining of the uterus. This usually happens about once a month, lasting anywhere from 2 to 7 days. The menstrual phase is the first phase of the menstrual cycle.
What process signals the end of one cycle and the beginning of another in the menstrual cycle?
The shedding of the uterine lining (menstruation) marks the end of one menstrual cycle, while the release of an egg (ovulation) signifies the beginning of the next cycle.
What happens in the ovulation phase of the menstrual cycle?
During ovulation, an egg is released from the ovary and travels down the fallopian tube, where it can be fertilized by sperm. This typically occurs around the middle of the menstrual cycle.
What marks the end of one menstrual cycle and beginning of another?
The menstrual cycle begins Day 1 of your period, about half way through the cycle you ovulate and the last day is the day before your next period starts. Day 1 begins the cycle all over again. The last day of your cycle tells you the length of your cycle, on average between 24 and 34 days, although longer and shorter cycles are still "normal".
