<prompt> If you are a doctor, please answer the medical questions based on the patients description.I take lo lestrin Fe regularly and have for over a year now. This past month I forgot one pill in the first week but now I am 2 and a half weeks into the pill pack. I had sex without a condom. Should I take plan b? Should I be covered? I take my pill regularly at 8 or a few hours before or after every day.  <response>: Hello misunderstand your concerned you missed the one pill during the course of the birth control pill then you have to take missed pill as early as possible or on the next day with regular pill. But you did not describe anything about your missed pill whether took or not. If you took missed pill as early as possible or on next day with next day pill: no need to take Plan B pill as efficiency of OCP does not decrease. If you did not take missed pill on nest day: then efficiency of OCP will decrease, and you have to use condoms next 7 days. So if you have not been taken missed pill already you did not use condom then you have to take Plan B pill to prevent the pregnancy. Hope this may help you Best regards
