what day should i start my birth control?!

start on sunday even if you are still bleeding (probably not likely if you started last friday). it will help you keep track of the weeks a lot easier if your starting every set at the beginning of the week. also, you should take it at the same time every day to keep your hormones at an even level throughout each day. i take it in the evenings before bed. if i try to take it in the mornings, it's just too flipping hectic and i totaly forget.
hope i helped!

You should start it either the sunday after your period started-- so the sunday that already passed-- or the day you start your period.
