text: you can take the birth control pill continuously, its probably the safest way... the nuvoring or the patch probably can be used in a similar way. i would stay far away from the depo shot that someone mentioned...i knew a girl that bleed for a month straight on depo...and with depo your stuck with it for the full 3 months (sometimes it takes 4 months to fully leave your system).  try looking into something like seasonal birth control pills (4 periods a year) http://www.pamf.org/teen/sex/birthcontrol/seasonale.html
