✔ 最佳答案
Some menstrual periods are very light; others are too heavy. In fact, there's no universal level of menstrual bleeding that's "just right." Menstrual periods vary for each woman, so it may be difficult to decipher what's normal and what's abnormal bleeding.
However, if you experience a heavy period, requiring a new sanitary pad every couple of hours, or if your menstrual cycle lasts longer than seven days — or both — you may be dealing with menorrhagia, otherwise known as heavy menstrual bleeding.
