If you took Plan B: One step and vomited about 2 hours later- you likely still absorbed enough to be effective. It looks like you took Plan B again about 2 and a 1/2 days after sex. 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.
