Firstly, let me tell you that pregnancy
is not possible with intercourse around the period as it is the safe period. It is during the mid-cycle, i.e., from day 11- day 18 of a regular 28-30 day cycle that chances of conception are more. So, there was no need to use an emergency pill at all. An emergency pill gives almost complete protection when used within the stipulated time. Withdrawal bleeding is usually seen as a pill-effect due to the hormonal
imbalance created by the pill. The next cycle also may be delayed and if she does not see her next period within 10-14 days after she is due, consult a specialist. Please use a regular form of contraception
in future and restrict the use of the pill to once or twice a year only. Hope your query has been clarified. Take care.
