They usually say that if you didn’t get them during pregnancy and your mum didn’t them, it is unlikely that you will develop them after a BA. I am assuming since you have been pregnant the skin on your breasts won’t be extremely tight either, i haven’t been pregnant before and i had 415cc from almost no breast tissue and i have no stretch marks but neither did my mum after having me. I used bio oil and cocoa butter a month leading up to my surgery to soften the skin as much as possible before hand, as surgeon said i could get them but 6 months on and still don’t have any xx
