what does a light period mean
Although the menstrual cycle varies from person to person, most women have a normal period approximately every 28 days. Each period typically lasts from four to seven days. The amount of blood lost during a menstrual period ranges from 20 to 80 milliliters (mL). Blood loss of less than 20 mL may be considered a light period. A shift or imbalance in hormone levels is the main cause of light periods. Light periods most commonly affect women who are approaching menopause because at that time in their lives women produce less estrogen, one of the hormones that regulates menstrual periods.
