"i began taking yaz about a year ago and i love it. while on yaz, i never noticed any changes in my mood, or my body.  however within the last few months i switched to the generic version gianvi hoping to save some money. at first i didn&#039;t notice any difference, but slowly i have been getting more and more emotional, and anxious....something that i have never had a problem with before. and now i have been having a breakthrough period for the past 15 days straight, while on my active pills. i am not sure if this is because of the gianvi, but i can&#039;t think of what else it could be. i will be switching back to yaz asap. it is worth the extra money. i do not recommend gianvi to anyone."
