"I was on Yaz for about two and a half years before having been switched over to Gianvi, which I've been on for a month now.  I feel like Yaz worked much better for me than this new generic.  I know that my body might need time to get used to it, but my period so far has been...not what I'm used to.  With Gianvi my period seems to be light to the point where I'm afraid I'm spotting and might be pregnant, and it's accompanied by gas and constipation, and some pretty nasty mood swings.  I never had this problem with Yaz. I'll be switching back to Yaz."
