There is no rule for periods. U should be comparing ur periods with ur earlier periods not to anybody else's

Hello, if you have mild bleeding for 6 days then nothing to worry.But prolonged heavy bleeding is really bothering issue because almost 80 ml of blood will be lost in each cycle .usually 20-30 ml of blood goes off in normal Menstrual cycle. Prolonged days of bleeding could be due to harmonal variation ,you can opt for oral contraceptives which regularises the periods .
