Is it ok to be this size bra at my age , hieght and weight ?

Im 13 , 5f6 and I weigh about 10.8 stone . But im not fat or anythin , I have big-ish bones and long legs and arms. (I sound freaky I know) , anyway im confused about my boobs! , im a 34b. But they seem to change their shape a lot ! Sometimes they become...

very full and nice looking , and then other times they become kind of pointed and the nipple becomes sort ov big and puffy-ish , it has a lot of effect on my self-esteem, I feel so embarresed and stupid typing all this ! I dont sleep with my bra on or anything. why do they keep changing shape? , is it ok to be this size bra at my age , hieght and weight ?
Please help !

haha its completely normal to be your size at your age! lol and by the sounds of it you are just going through a regular growth, there is nothing wrong with your chest, so don't let it worry you. people wont notice when your nipples are acting weird because they are covered so stop scaring yourself :P

Frankie is right, its the age your at , one you fully develop more then likely your breast/ nipples will settle down, dont worry about it, most girls go threw this, your not the only one.

I am the same height ,weight, age and bra size as u. creepy I know. but yer it is normal xx (:
