Okay, I know everyone says that you don't gain weight from BC pills... but that is complete BS. I was on OTC for a few years, then Nordette, then Yasmin for a few years, and now Zovia... All in all I've been in BC pills for seven years. Zovia has been the ultimate worst one because I DID gain weight. I did nothing differently in my diet. I work out 5 or 6 days a week and run about 20 miles a week. I'm 23 and very health conscious and have been 5'3 and 115-120 since I was 14 years old. THIS made me gain 15 lbs in ONE MONTH! That is obscene, even if it is just water weight. I even started eating salad with no dressing on it! I mean, what else is a girl supposed to do!?!? I can't bear Zovia just for this reason... I always had small B breasts and now they are D's! I called my doctor today to switch to Mircette and sooooo hope it works out better for me.
