21 Years Old, No Kids, 445cc round moderate profile implants

My breast augmentation is scheduled for May 3, two days from now! It's been scheduled for about 4 months, but I had been looking into the procedure and doctors since I was 18. A little about me - I'm 21, no kids, 5'4 and 130 lbs. I'm fairly athletic and weight train frequently. My doctor came highly recommended by multiple friends/other dances. The consult was a bit hectic and rushed, but the doctor was very knowledgeable and answered all the question I had. One of the nurses helped me use the imaging system to see how I would look with different size implants. I knew going in that I wanted at least 400cc, and the doctor said that the max he would put in my is 500cc. I ended up narrowing my choices down to 450 or 475, which I will decide between the morning of surgery.

Getting extremely nervous... not about the procedure just about the size. I'm nervous they will not turn out big enough but I feel like 450/475cc's already sounds like a lot... plus my doctor said the max he could do is 500. My current stats - 5'4, 130lbs, slightly athletic, 34a. Adding some wish pics to this post.

Some before photos... ugh
