Well, as we mention in our HBC Vulvapedia entry, (http://www.vaginapagina.com/index.php?title=Hormonal_Birth_Control#OK.2C_I.27ve_got_some_HBC_now._How_do_I_start_taking_it.3F) it's relatively common for doctors to say that it takes a month to become effective. So many patients hear that that it's actually become quite a huge myth!
This extended time period advice is based on the idea that if a woman is going to make severe mistakes in pill-taking, she's more likely to do it in the first few months while getting used to taking the pill every day.
In actuality, as per the prescribing information in every packet of birth control (which must be accurate by law), and verified by many experts, all hormonal birth control becomes fully effective against pregnancy after appropriately taking seven days of active pills. :)
