Birth control and big boobs

About 2 months ago I began the pill and instantly my body started changing. One thing I hate so much is the fact that my boobs are sore all the time and are a whole cup size bigger now! I'm falling out of my bras and I can't go braless and some of my tops and dresses like I used to. I'm not fond of this new breast size. I'm a dancer I've been used to smaller boobs my whole life. When I do decided to get off the pill will my boobs return to its original God-given size or am I stuck with these new boobs forever?
