Hi thanks for your question.
You have to take postinor 2
Postinor 2 can help to prevent you from getting pregnant, after unprotected sex,
The first tablet has to be taken within 72 hours (3 days) of unprotected sex.
The tablets are more effective if they are taken as soon as possible after unprotected sex.
You need to take 2nd tablet 12 hours (but no more than 16hours) after first.
So relax you have taken the medicine well within the prescribed limit.
Hope I answered your question.
