Im 15 im suppose to start aviane on Sunday and to be honest im afraid im not sexually active im on this because of my horrible cramps.(i have been trying to avoid this for 5 years with other medication prescribed by my doctor.) Im afraid of the side affects that i have read about and i don't want to take it but i just want my cramps to go away i was told im at a high risk of blood clots and high blood pressure. After reading all of these side effects i want to go back and get a new kind. My question is should i try it or should i switch right away?
