"i was prescribed kariva after another birth control became too expensive. i was afraid to try it out since there were so many negative reviews, but i am happy to say that this is a magical little pill (so far). i have not experienced any weight gain, moodiness, or low libido. my acne cleared up (i&#039;m 27 and have always battled with acne) for the most part. the only drawback is some mild discharge, but nothing to worry about. i love this pill!
