Doctor's answer:
The amount of menstrual flow varies from person to person, generally ranging from 20 to 100 milliliters. It is considered normal to change sanitary pads or toilet paper 3 to 5 times a day. The duration of each menstrual period is usually around 3 to 7 days. Menstruation can be affected by various factors, and it is normal for it to be early or delayed by up to one week, such as due to excessive stress, changes in environment and climate, poor nutrition, high pressure, or lack of rest.
