"i have been on gianvi for about 4 years. i was previously talking lo estrin but it made me really depressed and i never had a period. as soon as i switched i felt a lot better and i get a mild period the same time every month. it also really cleared my face up i get almost no breakouts and also didn&rsquo;t experience weight gain but everyone is different. i did recently get switched to the nikki version of the pill and it was terrible. i got lumps in my breast had horrible migraines and also experienced multiple hot flashes throughout the day. i finally got gianvi back and almost immediately this side affects went away. if you are on a brand of pill that works for you don&rsquo;t let them switch you just make them order it or find a new pharmacy"
