Bigger breasts after stopping birth control?

Hey. I have been on birth control since I was 12 due to a gynaey trying to stop my endo growing. I have always had small boobs however I came off birth control 3 months ago which I was on for 12 years. I have only ever had bad breast pain a few times in my life however I'm suffering from it a few weeks a month and think my breasts are bigger, is that normal after coming off birth control? TIA
