Answer 2

Three days of bleeding, which may seem short, is still considered normal as long as you're menstruating regularly. That means that every few weeks, an ovary releases an egg and estrogen builds a thick lining in the uterus called the endometrium, which the body will shed if fertilization doesn't occur.

The menstrual cycle, which is counted from the first day of one period to the first day of the next, isn't the same for every woman. Menstrual flow might occur every 21 to 35 days and last two to seven days. For the first few years after menstruation begins, long cycles are common.
