birth control
"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'll never know it is there. I used to faint during my period without the nuvaring - which I don'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."
