Question: how many days does a woman menstrual period last?
Answer: The first day of a woman's period is day 1 of the menstrual cycle. "Periods last around 2 to 7 days, and women lose about 3 to 5 tablespoons of blood in a period," says Belfield. Some women bleed more heavily than this, but help is available if heavy periods are a problem. Find out about treatments for heavy periods.
