Don't worry too much if your an a cup or below its very unlikely you'll have much cleavage push up bra or not it sounds completely normal I had very little cleavage at a small c cup when I started nbe because of my body type and size of my breasts now I have great cleavage even braless
You say your growing which is so great so don't be frustrated be happy growing at all is much harder if you start very small or if your underweight so your lucky to find something successful in just a few months I'm sure more fullness will come if you keep at the nbe but you really worried you could also try a pump that helps round out breasts a lot I think noogleberry helped but really the bigger they get the more cleavage, there are also shaping bras that help push more fat to breasts like bradelis.
I also read you wear bras that don't fit properly wearing a properly fitted bra or braless could help you weird as it sounds wearing no bra improves sagging I think mostly because badly fitting bras do more damage than good and most women wear bad bras it really works I m a g cup and mine look better since going braless.
