I had been on nuvaring for about 7 months or so when I decided to stop using it for the most part I had no side effects such as spotting or bleeding in between periods but the symptoms I did seem to have to the highest degree was severe depression, crazy mood swings, pain on my lower left side. But the worst symptom was the severely painful headaches I was getting twice a month or so. Now since I have stopped using it I am nauseous.I have cramping also getting headaches my breasts are so sore . This is so crazy I never thought that using the nuvaring would have this kind of effect on me I feel like I'm pregnant with all these symptoms its nice to know that I'm not alone here though. I also wish I knew how long I was going to feel like this.
