Well like poster above said, its ok to miss the first one. If this keeps on happening you're in big trouble girl! Just be responsible enough to take it daily especially if you're a teen (I hope your not anymore). Getting pregnant or having a baby isnt so easy.
I think it would be better if you stopped taking the pill altogether until your next period. Its better to be safe and you might get pregnant. Better use a condom for the next time you want to have sex!
