I felt the exact same, got my boobs done at only 19 (now 21) and 100% want multiple kids in the next 5-10 years, i follow some youtubers who’ve had children after a ba and have no issues, they wore a post op bra again throughout the whole 9 months and most don’t breast feed. i decided I probably wouldn’t want to spend that amount of money outright when i have a little one to think about, so did i for myself while I don’t feel any guilt about it xx
