Menstrual Cycle


The menstrual cycle is a remarkable and essential aspect of a woman's reproductive health. It is a recurring process that typically occurs every 21 to 35 days, involving a series of hormonal changes and events. During this cycle, the ovaries release an egg, known as ovulation, which holds the potential for fertilization.

If fertilization does not occur, the uterine lining that thickened in preparation for a possible pregnancy starts to shed, leading to menstruation, or a woman's period. This monthly bleeding typically lasts for 3 to 7 days and marks the beginning of a new cycle.

The menstrual cycle is a complex interplay of hormones, and its regularity serves as an essential indicator of a woman's reproductive health. However, variations in cycle length and symptoms can be normal for different individuals.

Understanding and tracking the menstrual cycle can help women take charge of their fertility and overall well-being.
