Obvious size and shape asymmetry after breast augmentation. How likely will this correct itself?

I had surgery this week. I was a 34AA and wanted large B/small c. My PS said one breast was bigger than other, so he used 275 CC smooth round moderate plus On one side and 300 on other. He had to create a fold because I had none to begin with. Post surgery when I took my bra off, I cried. I can immediately tell which one is the bigger implant. One bottom is also very flat. But if it does settle/round it will then be lower than the other side. What's likelihood of them becoming symmetrical.
