hi i would not worry to much your be surprised how much they can put on at the end and not forgetting you may just stay small as well. the sagginess could be ready for the inflow of milk. but not to worry see your midwife or what ever you have in the usa. sorry english. good luck
what if my breasts havent grown enough during pregnancy? will this affect milk formation? . also my breast does not seem to be firm its feels loose and saggy yet small.
