"i love gianvi. i used this for birth control and for pmdd. i&#039;ve had zero moodiness, very little pms symptoms and very light periods. i&#039;ve been taking gianvi for 4+ years and can&#039;t say enough great things about it. my local pharmacy recently switched to a different brand (same hormone combo) of this birth control and i felt horrible, headaches, mood swings, stomach aches. please be sure you are getting gianvi and not a different name brand."
