Hello and Welcome to ‘Ask A Doctor’ service.
I have reviewed your query and here is my advice.
How many hours after intercourse she took postinor - 2?
Postinor-2 is an emergency contraceptive
only. Postinor-2 is not intended as a regular method of contraception
It is used to prevent pregnancy
when taken within 72 hours of unprotected intercourse
. It is estimated that Postinor-2 will prevent 85% of expected pregnancies. 95% of expected pregnancies will be prevented if taken within the first 24 hours, declining to 58% if taken between 48 hours and 72 hours after unprotected intercourse.
It is not known whether Postinor-2 is effective if taken more than 72 hours after unprotected intercourse.
You already used barrier contraceptive so nothing to worry. Chances are very less but still get UPT done if she misses the cycle.
Hope I have answered your query. Let me know if I can assist you further.
