No kids so body enhancement

Was told I can't have children of my own. So I have been thinking since I cannot have children of my own and other options to have children are way too expensive and we wouldn't be able to afford children or take care of them.... I want to get back into shape, get my degree and into my career. I really would like to get my breasts done since all this weight gain and loss has made them less full and a bit saggy. I have been doing a lot of research and it takes a few days to recover so should I get them done before school so I don't have to miss a few days to a week? The place I found will allow me to do payment plans which makes it more affordable to do.
