Hello, I am 21 weeks pregnant with my first child. I am very much dedicated to and looking forward to nursing him for as long as he wants to, but I am starting to worry that I may have trouble with it. I have PCOS and just found information on the forums about how many women with PCOS struggle with a low milk supply. I know my mother and sister both have, although I don't know for sure if they have PCOS (though I think it is likely). My breasts have always been pretty small (between an A and B cup, I would say, and I have wondered for a few years if that could be because of hormonal issues when they were developing. I'm concerned that what is there is just fat and underdeveloped mammary tissue. Since I got pregnant, I have been expecting (according to what I read in all the pregnancy literature) that my breasts would grow, but so far they haven't at all (I think my areolas have though - TMI, but I don't know if it's a good indicator or not). My latest 21-week update said to even expect some leakage. Is it a bad sign that my breasts have not grown at all? I'm not trying to borrow trouble here and have unnecessary worry, but at the same time, I really do not want to give my son formula, and if there is anything I can be doing now to help or things I could have prepared to start taking after birth, I would like to just be prepared emotionally and practically for potential problems so I don't get overwhelmed in the post-partum period. Any input or advice is greatly appreciated. Thanks!
