"i really enjoy the nuvaring. i cannot take birth control pills because they contain lactose and i am allergic to dairy. the nuvaring is super convenient  and easy to use. if you put it in correctly you&#039;ll never know it is there. i used to faint during my period without the nuvaring - which i don&#039;t now. also i barely have any cramps with nuvaring and have shorter period. the side effects that i endured with nausea and breast tenderness for the first month. also i have had some weight gain, and loss of sex drive - but both are minor. the most prominent side effect was breast enlargement - i went from a 32c to a 32ddd."
