After taking an emergency contraceptive pill, when should I start using regular birth control again?

ANSWER

If you use condoms, a diaphragm, or a similar type of birth control, start using it right away. If you take birth control pills or use the patch or a vaginal ring -- but missed some doses -- start using them the next day. But you'll need to use a backup, like condoms, for at least a week
