Breast augmentation!

Hi all.

I'm having BA in the morning and feeling very scared.
I'm 5'5 and weight 9 st. 32B at the moment. I want to be a full 32D.
Having silicone over the muscle but still haven't decided on the size yet.
I ordered the 335cc and the 360cc. Really stressing out about this and I just really want to get it right.
Any advice would be appreciated.
Thanks.

Jessie. x
