When do I start birth control again?

I have been on birth control before, but I went off it for a month & now I want to go on agan, I have a package of pills & I got my pieriod on sunday & its stopped by today (thursday) so I know for linessa there is when you start the pill the day you begin bleeding & the sunday start (the sunday after your pieriod begins) does this mean I start taking birthcontrol this sunday? (in 3 days) for should I have started already?

Just start today with pill #1 and take them as you used to. But remember that for the first month you have to use aditional protection (condoms). Next month the protection will be fully in place.

yes I've been onthe pills before also, so yes take it this sunday
