Well I was on the Nuvaring for two and a half years. I was taking it purely for the birth control, my periods prior were fine. I had no side effects until about 2 years in. It was December of this year and I started pulling over on the side of the road with horrible panic attacks. I was scared to drive feeling like I was about to pass out. I started going to and acupuncturist in hopes of relieving my anxiety. Right away he said it was my hormones in the birth control, but I didn't want to believe him. About 3 months later I asked my Gyno and she swore that the hormones from the birth control would not cause anxiety. Well slowly it got worse. I was panicking on an airplane- which I had never done before. I had panic attacks in the middle of the day, when I saw the sun set; I was feeling claustrophobic in my own house. I was constantly nervous, and had lost my appetite. So I decided to take out the nuvaring. Within 4 hours I felt better. It has been amazing the change I have felt. I am not 100% feeling better, because I scared myself with bad thoughts while feeling nervous, but I am on my way back to my old self. I caution the use of the Nuvaring, only because it caused me to feel like I was going crazy, and it took years to see those side effects.
