Hello ladies. I have a question... I'm 22 and I have a complex about my small breasts. I'm 5'7" with broad shoulders, and I would like a more feminine figure. I heard that hormonal therapy can help breasts grow. Will it work after breastfeeding? Should I see a gynecologist to get a prescription for this or is it not effective anymore? What do you think? And also, if I lose weight even by 1-2 kg, the breast goes away first, it's not just small, it's completely gone, if I don't wear a bra, then it's hard to tell where it is...
