Contraplanll® is two capsules you take together by mouth within 72 hours (3 days) after unprotected sex or birth control failure to help prevent pregnancy. The sooner, the better.
How to know it worked:
You will know Contraplanll® worked when you get your next period, which should come at the expected time, or within a week of the expected time. If your period is more than 5 days late, it is possible you may be pregnant. You should get a pregnancy test and follow up with your healthcare provider.
