"i&#039;ve been using nuvaring for about a week, switching from the pill aviane. i&#039;ve been on about 6 different types of pills since 2008 and each has made me extremely irritable with horrible mood swings. not so much with the lower dose pills but still to a point that interfered too much with daily life. nuvaring has the lowest estrogen for combined hormonal birth control and doesn&#039;t go through the gastrointestinal tract, and so far, it&#039;s been great. i do not feel crazy anymore. unfortunately i have to be on birth control for ovarian cysts, so i am thankful that this is available. it&#039;s a bit pricy but i&#039;d pay more to keep craziness at bay. i hope that it continues to work well."
