Does not being busty count against you in AM?

Im not busty I have the same body type as Niti Taylor maybe even smaller boobs than her. I'm trying to gain weight IDC if i lose my small waist i just want to be a bit plumper. The only thing plump about me is my thighs and butt. I feel like im getting rejected for not being busty enough in AM prospects. I try to wear things that accentuate my curves that i have like midi fitted skirts, or high waist jeans but i feel my chest is holding me back. Like my bloodwork is fine and my periods are regular, I have no pcos and no disease related to reproductive system. So what im flat like Ill gain boobs when im pregnant. I think my mother also got breasts after having me though even she said im too flat.
