I'm so glad I found this website! I'm 25 and I've been using Nuvaring for 3 years (Ortho-tricyclen and low dose for 5 years before that), and I also found that the bad side effects of Nuvaring came on gradually. I've been experiencing nausea, headaches, abdominal cramps and diarrhea, anxiety and depression, irritability, fatigue, and low to no sex drive. Because they all came on gradually, I really didn't attribute them to Nuvaring. This past month, I accidentally left the ring out for 10 days instead of 7 to have my period, and since I've put the ring back in, I've been VERY nauseous (this has lasted for 4 days so far). After reading all of your comments, I'm going to remove it for good. I just hope the nausea goes away soon.
