Periodlängden
Periodlängden refers to the duration of a menstrual cycle, from the first day of one period to the first day of the next. This cycle is regulated by hormones and involves the thickening of the uterine lining, ovulation, and if fertilization does not occur, the shedding of the uterine lining. The average periodlängden for most women is around 28 days, but a healthy cycle can range from 21 to 35 days. Factors such as age, stress, diet, exercise, and hormonal imbalances can influence the periodlängden. Irregularities in periodlängden, such as cycles that are consistently shorter or longer than average, or that vary significantly from month to month, may sometimes indicate an underlying health condition and could warrant medical attention. Tracking periodlängden can be a useful tool for understanding one's reproductive health and for family planning.
