22 Year Old, Slim Athletic No Boobs, 5'9"

I'm went in for a consultation with synergy plastic surgery based on all the reviews and was fitted with a 500cc silicone. I'm not sure if that's large enough given the pictures on my wish list. But at the same time the pics I've seen of people on here with 500cc seem big! But again...idk if I have enough breast tissue to cover that much??? My preop is on Monday so I'm definitely going to be asking about larger sizes! I don't want any regrets, any ideas?

I had my pre-op and we're going with high profile 520/500 on one side and 485 on the other most likely. It'll depend on the symmetry during surgery! I can't wait????
- High profile because I have a narrow breast diameter and we don't want side boob. I do hope I get a little bit of side boob though. BUT! I'd rather have nice cleavage and a full upper pole I think.
I'm hoping for full D's starting from a barely there 34A/34AA so we shall see. Just super excited!! Surgery is in 7 days. Dr Kerr said it'll probably take a couple of months for the implants to drop and they'll be really high and tight for a while.

So I'm several hrs post surgery!! Yaay!! I can move around but there's definitely pain (4/10) even while I'm on oxy. I haven't lost my appetite and I'm taking anti nausea meds which helps a lot! The girls are bigger than I expected which is awesome but I wouldn't mind if they shrunk once the swelling goes away.
Dr Kerr says because of my smaller frame up top it'll take between 6-12 months for them to be in their true final form.
Process was super simple and straight forward. I woke up wanting water and was able to leave almost as soon as I woke up:)
Being up and about it's defiantly making me drowsy so I'll update tomorrow again after I get these bandages off??
