If you are taking your birth control pills correctly & consistently, then you are protected from pregnancy. The chance of pregnancy would be low. While taking Plan B was not harmful to you, unless you had recently missed pills, Plan B was not necessary.
After taking Plan B, some women may experience irregular spotting or bleeding. Your period may be a little later than usual. It may be lighter, heavier or spottier than usual. Continue to take your regular birth control pills every day. Your period should return to normal within a month or two.
You may also continue to use condoms as your back up method for added protection.
