"i&#039;ve been using nuva ring for about 2 months now. for the most part i&#039;m pleased with it. and it&#039;s very effective. the only problems that i have is the side effects it may cause. nausea, headaches and occasional cramps were present. above all i&#039;m pleased with this method. i was very skeptical about using birth control, but then i talked it over with my doctor and we both agreed that this would be right for me."
