The normal amount of sanitary napkins used by women for menstruation is about 10-20 pieces of sanitary napkins, if it is less than 10 pieces, it means that the amount is less, if it is more than 20 pieces, it means that the amount is more. Because women’s menstruation is the shedding of the uterine lining, some women’s uterine lining shedding faster, so there will be the phenomenon of the first 2 days of menstruation in large quantities, when it is finished shedding there will be no vaginal bleeding, so basically there is no more on the third day.
