Before getting your breast augmented, I would seriously consider seeing what changes could be made to my body from exercise. Since my mom died from breast cancer I'm not a big fan of doing anything to my body that could mask or hide cancer from future screenings.
You may also consider getting them lifted instead of augmented.
What ever you choose don't just think of this time in your life but fast forward 10-20-30-40-50 years down the road.
Please be very careful. Some changes just aren't worth it in the long run.
