Hello ma'am.

The efficacy of unwanted 72 is as follows:
-Taken within 24 hours: 98 %
-Taken between 25-48 hours: 85 %
-Taken between 49-72 hours- 58 %

If you wish you could conduct a home pregnancy test, 2 weeks after the suspected date of conception or on or after the first day of a missed period.

Hope this helps.

Best wishes.
