Okay so I've been on the pill for almost a month now, but my pharmacist keeps switching brands on me almost every month. I know they say your boobs don't grow, but they almost like swell. Well, I've gone from a C to a DD in the past year, and now, my bra is getting too tight again. Is this because of the change in pills or just the way my body reacts to the pill in general? Is this normal? I'm not complaining necessarily, but I don't want to keep buying bras. HELLLLLPPPP
