YANAD or a pharmacist, etc., but maybe you give me some idea how long I need to take my birth control pill before it is effective as contraception.

I just began taking Reclipsen, a generic monophasic combination pill. I hadn't been using anything before that. I started the pack the Sunday after my period (which began last Friday, so this is day 4). How long does it take to become effective as a contraceptive?
I swear, this is not in the product information. The Walgreen's online pharmacist could not find it either. Online, I've found people saying anything from "immediately", to "7 days", to "finish a full pack".
I promise I will not rely on the internet (possibly unless someone can direct me to an official manufacturer's website or something).
