That is unusual, sweetheart. I would talk to your doctor about it and get him to check if there is any health issue that is causing this. When you have dealt that out, there are, fortunately, special bras that can be bought (not cheap sadly) that will balance the two breasts. Or else you can use the old "chicken fillets". Your doctor will tell you if this will settle down, or whether something needs to be done.

I can't believe I'm doing this but I'll post 2 pics.

Most women have one bigger than the other, and they could keep growing for another couple of years. After following Singwells advice by seeing a doctor, If I were you I'd continue stuffing until age 18, save up your money and if by that time it still really bothers you have them done.

It is normal for a slight size difference, but that much is not. You can try to see if birth control pills will help with development, but will probably need surgery to correct that much of a differnce. Mine are about a cup in difference.

You should have started to even out by now.You should talk to your MD and see if he can do a mammogram, looking into to futher diagnosis.

I agree with talking to your doctor to make sure there's not something actually wrong, but I'd also say don't worry. Putting both pieces of padding on one side seems easy and reasonable for the time being. I also second the birth control suggestion. In my experience and seeing other girls on it, it makes breasts fill up and out- to be TMI here, I went from pretty much your left side picture to your right side picture, almost exactly.

I was 16 when i had my first surgery, I was a D cup on one side and had no breast (like a child) on the other. I have had 3 surgeries thus far(now 37), it is very very hard to find a surgeon to do the surgery so young but they are out there. Many people tell you to wait to you are fully developed however I know it is different when you are living with it. Some things to be careful of, insurance companies will give you a very hard time in covering the surgery, I go through it every 7-10 years as you are suppose to replace your implants within that time. My suggestion as I am one of the many suffering from a silicone rupture--ask for saline if you dedide to do it. The battle with the insurance isa constant uphill battle but it can be one---having your doctors find the right codes, and fighting the insurance company with the Insurance commissioner in your area can help---one of the famous quotes i hear all the time is "You can live with this"--yeah tell that to a 16 year old---my argument ever time is why would you cover a woman who looses a breast to cancer, but not someone who was born that way---why should we live with it--but they need it to feel more like a woman, granted--knock on wood it is not fatal to us, however we still want to feel just as complete Keep your chin up you will be able to correct this--although it is a constant battle, it is worth it in the end to feel completley normal Good Luck
