Hello, I have gone through your query and understood the concern. Firstly, please do not stress as you had the emergency contraceptive within the stipulated time interval and so, you are safe. Secondly, please note that ovulation occurs two weeks prior to the onset of the next period and if you did not have the intercourse around this period, you are naturally safe. Lastly, Primolut-N is not going to be as effective and will cause further hormone imbalance. You may or may not see withdrawal bleeding depending on the basal hormone milieu. The emergency pill you have consumed contains high doses of progesterone and thus creates hormone disturbances; you may see a delay in your next natural period by a week or two. See a specialist for further help if you become overdue by ten days. Hope your query has been answered. Take care.
