"i actually loved the nuvaring! i did have some side effects such as cramping and breakthrough bleeding, as well as the ring actually sliding out. i know it is unheard of, but i did gain weight on the nuvaring, nothing major but a good 5 pounds! i used the ring for about three months.  i recently switched to lutera to see if i like that better. i will post a review on lutera when i use it longer."
