Plan B is an emergency contraceptive pill that helps prevent pregnancy. It is most effective when taken within 24 to 72 hours after unprotected intercourse (about 75% to 80% effective). Some research states that Plan B can still be somewhat effective when taken as long as 72 hours (5 days) after unprotected sex.
If it has been longer than 5 days after your unprotected intercourse, unfortunately, there is nothing you can do to prevent pregnancy. You will have to wait until your next period. Until then, use condoms or abstain from sex. If your period is more that 1 week late, do a pregnancy test.
You may want to consider beginning a long term method of birth control like birth control pills, patch, vaginal ring or the DepoProvera injection.
Family Planning Plus clinics offer gynecological exams, birth control, pregnancy testing and emergency contraception for little to no cost, depending on your household size and income. STD screenings are free for men and women of all ages. Please feel free to schedule an appointment at any of our clinic locations.
