Breast Augmentation and Breast Implants Discussion

I got my BA a 8 days ago. I was barely filled an a cup prior to the surgery. I told my surgeon I wanted a full natural look, full c small d. I told him probably like 375cc because I looked at tons of photos of before n afters of women who were similar to my weight height n breast size. However my dr said don't compare cc's with others bc the same number of cc's can b totally different on two people. Im about 5'6 and weight around 123lbs. And im very thin on top. I told him I wanted to b proportioned since im a lil thicker on bottom. I did go to 2 diff drs for consultantions and at one office they had my try implants on in a sports bra n I chose 400ccs. However I ended up going with the other dr and told him how I tried the implant on n he said that doesn't always help bc ur real result will look diff. I then told him how I heard a lot of women say they should have gone bigger after they had their surgery and he said that he tends to go a lil bigger than what the patient wants bc of that. He ended up placing 475cc silcone implants and I still feel small. I went to my post op apt 3 days ago n told him I feel I went to small. He said he put the biggest implant in me that would still look natural and wait a month until they drop and will b fuller. But I hear that once they drop and are not swollen they get smaller. Im confused n upset I spent all that money and time and don't feel happy with the result. Will they get bigget once settled or.smaller???? I feel like I want to already schedule another surgery to go larger only a wk after!
