Extremely low.: Intact condom used properly is about 80% effective. Plan B is about 75% effective. Used together, you should be very safe, but you may want to choose something other than Plan B for birth control in the future.

Pretty low.: Plan B One-Step is up to 89 % effective when taken within 72 hours (3 days) after unprotected sex. It can reduce chance of pregnancy by up to 95% if used within 24 hours. It continues to reduce the risk of pregnancy up to 120 hours (5 days) after unprotected sex, but is less effective as time passes. Using the condom increases the level of protection.
