Welcome to HealthCareMagic,
Yes, you can continue to take Primolut N
, to postpone your menstrual period for few more days, but the dose of Primolut-N tablet for postponement of period, is one tablet thrice daily (6am,2pm & 10pm).
Hope you found my response to your query informative and helpful.
With good wishes,
