birth control
"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."
