Hello..... It's given to restore periods.. You take this tablet for 3 day and 4 to 5th day you will have your periods thats called withdrawal bleeding.. So sudden stopping of tab causes menses.. Think in other way round ... If you want to postpone menses you can take it for three, four days near your menses so that menses occurs 3 to 4 days after the expected date.. That's postpone of period. So it's used for both purpose.
