5%: Plan B is 95% effective if taken within 24 hours after unprotected intercourse. There are no studies suggesting that this is improved by taking it immediately. Now you need to start a reliable method of contraception. These are all more effective (pills, patches, rings, IUD's, shots, and implants). Be safe.
