omg haha, dont listen to gfam...
im sure youve heard this before but...
everyone grows at their own pace, blahblahblah.
so dont be in a rush.
big boobs SUCK. back problems much???

HAHHHA!
You DO NOT wan't big breasts.

Be happy that you dont have to wear bras, and can see down your chest, sides and stomach without moving them.

If you have big breasts, say goodbye to that nice back tan in summer, when you lay on the beach you have to dig two holes in the ground.

Say goodbye to being comfy when your laying on your stomach in bed.
Say GOODBYE to wearing low cut shirts and not having anything fall out.
Say hello to wasting 50 dollars on a decent bra, and having to change them when you grow another size.
And finally, say a BIG HELLO! to guys talking to your chest instead of your face.

Trust me, big breasts suck and give you ALOT of unwanted attention. Big cash blower, too.

Don't worry about it every one grows differently usually breast for some people take a little longer to get bigger. It's only not a big deal if you don't make it one. Your normal so don't worry it will happen and soon

you are just 13...you have other things to concentrate now..your breasts will develop when its due

My sister was 16 before she got breasts - now she's absolutely gorgeous! I guess it was worth waiting for!

same with me. I'm not very big either . I'm 13 too and when I look at my two best friends I can really understand that diffrent people grow @ diffrent rates. Like one of my friends in the same age as me (we were all born in the same week.) and she is a size 32 B!! the other is a size 30 A. And I'm a size 36 A. it all comes at diffrent rates but most of my older friends say big boobs look great if they aren't to big but kill your money and back. hahaha

I only got my breasts when I turned 15

don't stress hun
I spents night crying about it
DONT
they will come
if they havnt by 16-17 go see a docter

dont worry im 23 and my breast stopped growing after I got my period im only a 36 c and they havent even gotton any bigger

u have a lot of time yet...many people grow at different times...same with guys...I was an early developer and hated it as I got hair down there etc before most of my classmates and hated taking showers...so I can understand how you feel, even though its the other way around...but dont worry...it will happen and when it does, maybe you will catch up fast

why do you want them seriously is it just to impress guys?

no I can care less about impreesing guys, it was just a wuestion.

Good you should feel like an alien, buy some on ebay!
