wait for boob job?

So I just had my first child 4 months ago and I stopped breastfeeding at about a month and a half due to mastis then loosing my supply. Well the boob that got mastis is completely ruined, lost its shape, floppy, and doesn't sit right in a bra. I plan on get breast implants but I also plan on having another child in a few years, I would rather have my boobs done before then, but I don't want them to get ugly again... any tips ladies ? Lol
