Is it possible to have breasts grow much larger overnight?

Um last night when I went to bed all my bras fit fine maybe a little snug. Im 14 and I had a B cup size. Well when I woke up every thing was fine until I went to put a bra on. none of them fit and one of them broke. I used a measuring tape to measure my self and found out I now had a C cup. So I went to my friends house and just borrowed hers. But is it possible to grow that much overnight because I don't know if I want to ask my mom to go bra shopping? Please Help.
