welcome to HealthcareMagic
A delay in periods of 3-4 days or even a week is normal and it does happen .Nordett is a combination pill and is used as a regular contraceptive
and since you take it in high dose as emergency contraceptive it does work but the only problem will be that it will disturb your periods.So since there is no emergency pill in your country there is one thing you need to understand if you use this pill it will create hormonal
imbalance and lead to irregular periods
.The better option is if you are sexually active and have sex more than once a month then use Nordett regularly for 21 days and give a gap of 7 days by which you will get periods.Doing this will help you to avoid pregnancy
as well as maintain your regular cycle.
