Boob size probs...

I am 15, 16 in March. I've had my period for over a year. My bra size is a 34 B. But I hate it... I know this isn't very big at all, don't get me wrong. But they feel so big due to my body size. I feel so awkward with them because I'm only 5'2" and about 100 lbs. I need some confidence I guess, lol. Will my boobs probably get bigger?? 😞
