Your are just 13 years old, your body is still changing and will continue to do so for at least another 5 years. Will you remain a 34B or will your breast grow larger? Only your genes now for sure.
Right now what you have is still a work in progress. You may stay a 34B but as you body continues to go from that of a little girl to that of a women more changes will occur. These changes may be more subtle as the body reshapes what it has already changed. This is when the final shape of your breast will occur.
Right now though enjoy what is happening to your body for these changes will never happen again. The next time you body will have any major change is when you are post menstrual in about 40 or 50 years and gravity kicks in with a vengeance.

When you see giant spherical braless breasts, chances are they're not real. As you grow (and you likely will) they'll round out and drop a little bit.
