I had mine done 3 years ago... after back to back pregnancies, by breasts were not what they were. I never minded having small perky breasts but after was all said & done, I had saggy little teabags :s Plus I had noticable asymmetry. AA on one side, A on the other.
I've never regretted a single day of it. I had the most awesome, easy recovery ever. I didn't go big.. I'm only a small C. Frankly, none of our friends even noticed I had them done. They normally saw me when I was wearing a Victoria's Secret miracle bra. After the surgery, I went to wearing just a bralette. Not much difference fully clothed.
Implantinfo.com is where I did all my research beforehand & they have a board of lots of helpful ladies over there

Good luck with whatever you decide!
