YES, you can start anytime you want, BUT you have to use a back up BC method for 7 full days.

It takes 7 days to be protected, but that only counts for your VERY FIRST pack =)

Definitely, you can start any time. Doctors usually only recommend waiting to start until your first period because they want to make sure you aren't pregnant.

Start any time, defiently start on a Sunday though, which most doctors will reccommend. Its the same thing as after having a miscarriage or abortion. You start effectively the following Sunday. Also, taking birthcontrol pills might help induce regular periods.

There is really no need to start on a Sunday. The only reason that that is recommended is so you can look at the pack if it has the days listed and know which pill to take because it says the date on it.

However, I know my birth control comes with a sticker with the days on it you can put over the printed on dates so it fits to how you are taking them.

all I said was its simply reccomended

Sorry if that sounded harsh in any way. I didn't mean for it to come out threatening. You said "definitely start" on Sunday, so I was just informing her that it isn't necessary if she's interested in being protected ASAP.

Oh and on that note thanks PenguinsRus, also if you are choosing to be sexually active still use a back up method for about a month or so into using BC until it regulates itself into your system
