birth control
"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'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'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."
