The menstrual cycle represents a natural biological process in a woman's body, designed to prepare for potential pregnancy. This process typically initiates in the late period of adolescence and persists until menopause, which usually occurs around age 52.

Defined by the time span between the start of one period and the beginning of the next, the menstrual cycle is regulated by a complex hormonal system. The length of a regular menstrual cycle varies considerably, generally ranging from 21 to 35 days in adult women and 21 to 45 days in adolescent girls. Although the 28-day cycle is often mentioned as the standard, it is simply an average, not the definitive norm for all. The regularity of a woman's cycle is better determined by its predictability and the consistency in length over a period starts time.

During the menstrual cycle, hormonal changes cause the uterine lining to thicken in preparation for a potential pregnancy, and an egg is developed within the ovary. This egg is released during ovulation, marking a woman’s peak fertility period, pregnancy occurs approximately 5 days before and 1-2 days after ovulation. If the egg remains unfertilized, it leads to the absence of pregnancy, followed by the shedding of the uterine lining, known as menstruation, thereby restarting the cycle.

Menstruation, or a period, involves the regular expulsion of blood and mucosal tissue as part of the menstrual cycle. Typically lasting 2 to 7 days, this process involves the release of the uterine lining through the vagina and marks the commencement of the menstrual phase, a cycle lasts initiated when the previous cycle’s egg is not fertilized.

Generally, menstrual periods are absent during pregnancy and often do not resume immediately during early breastfeeding. Menopause, the cessation of menstrual periods, typically occurs between ages 49 and 52 and is confirmed after a third period begins a year without menstruation.

The Period Calculator is a practical tool for estimating the dates of menstruation and the most probable days of ovulation in a calendar view. The days of menstruation are characterized by bleeding and discharge, while the days of likely ovulation indicate when ovulation is most expected.
