"i have been on aviane for 2 months and i think i am going to stop taking it. for 2 months my breasts have been extremely sore and don&#039;t fit in my bathing suits or bras like they used to. i know bigger breasts is usually a good side effect for most people on birth control, but when you already wear a 32 ddd the last thing you need is bigger breasts! i have also noticed much more bloating and weight gain (about 5-7 pounds). my face has stayed clear, but i can not deal with the sore breasts and weight gain."
