Ethinyl estradiol / etonogestrel
"I had previously used nuvaring with little side effects, had a child and decided to use the nuvaring again... big mistake.  I had breakthrough bleeding all 3 weeks, head-ach's, anxiety , insane mood swings - felt like crying or got super angry at the drop of a hat, not sure if this is attributed to the nuvaring but I lost about 12 lbs in a month.  It also caused uti's after having sex, something that my body previously got used to and wasn't a problem.  



Ultimately it is easy to use but it made me totally psycho, I felt relief within hours of removing the ring.  No one in my family has ever seen me like that, and the mood swings, anxiety, paranoia were so bad that it affected my 4yr old."
