S.R.
Are you taking birth control? If so, it may be that. When I started using the Nuvaring I thought it was the best thing ever. Six months down the road I began to have bad migraines. I never suffered from headaches before. One night I had dizziness as if I had been drinking. I became sick and lightheaded. Someone metioned to me that it might be my birth control and so I stopped using it and I immediatley started feeling better.
