I would just like to get advise from anyone who has been taking birth control pills. I would like to start taking it as a means of preventing pregnancy but I am quite confused on how to start it. I was given Microgynon 30ed (28 pill pack), I was told to take it on the very first day of my menstruation.. I noticed that the pill has corresponding days indicated in it. Mine starts on a Sunday... My question is what is my period starts on a different day like for example Friday.. Should I still take the Sunday pill (which is first on the pack) or I take the first Friday pill? Will the whole pack still corresponds to the date? And how soon can it take effect after I take the pill that it will protect me from being pregnant. Do I have to wait a month and use a backup method? Im sorry for too many questions but I hope someone can enlighten me pls. Thanks
