"i started taking kariva when ortho tri cyclen lo became too expensive for me.  i have been on kariva for the past 4 years.  positives: predictable 5 day periods, no acne, less moodswings. negatives: weight gain (20 pounds), no libido whatsoever.  i was able to deal with the side effects for 4 years(my poor boyfriend), and now i&#039;ve had enough. i&#039;ve stopped taking it, immediately lost 5 pounds, have a great libido again, and find it easy to track my period with p-tracker app. "
