Relax, you're ok: Plan B is reportedly 95% effective if taken within the first 24 hours after unprotected sex. Exceptions would be if your body weight is elevated over 165#, as it becomes slightly less effective. If you are pregnant, a home pregnancy test is usually reliable about the time of your missed period, and definitely a week after. Insist on condoms in the future to avoid risk of both pg and infection.
