"i have been on ortho tri-cyclen lo for 7 years and it has worked very well for me. no pregnancies, even if i missed pills every once in a while. i&#039;ve gained some weight, but not much, and have had very predictable, short periods (3.5 days). i also have not had problems with mood swings. sadly, i can no longer take this pill because my insurance no longer covers it. i am going to try the nuvaring next, which i am very nervous about because i&#039;m not sure how it will affect me. wish me luck!"
