Final answer:

The average menstrual cycle lasts 28 days with variations ranging from 21 to 45 days, and ovulation typically occurs around the 14th day. Menstruation lasts about 4 to 5 days, but it can vary from 2 to 7 days. These variations can affect fertilization timing and menstrual cycle regularity.

Step-by-step explanation:

The average menstrual cycle without fertilization typically lasts 28 days, but it is important to note that there is considerable variation among individuals. The cycle can range anywhere from 21 to 45 days, and each woman's cycle may vary from month to month. Identifying the exact day of ovulation can be challenging due to these variations, which signifies that even if a couple like Isabella and Omar aim for sexual intercourse around day 14 to increase the chances of fertilization, they might not succeed if Isabella's actual ovulation day differs.

Menstruation, which is also known as a menstrual period, generally occurs when there is no fertilization, resulting in the breakdown and shedding of the uterine lining. A menstrual period typically lasts about 4 to 5 days, though this too can vary, ranging from 2 to 7 days. The cycle then repeats itself, beginning with the follicular phase, followed by ovulation around the midpoint if the cycle is close to the average 28-days, and possibly ending with menstruation if no pregnancy occurs.

If a woman's egg does not become fertilized, her body will begin to shed off the uterine lining, this is called endometrium, and is part of the overall menstruation process. For most women a typical menstrual cycle will last 28 days. The cycle begins on day one of a period and continues until day one of her next menstrual cycle. On average, most women ovulate on the fourteenth day.
