I have went from a D to a DDD and my breasts have horrible sm I have them on my stomach too though it looks like gouges its horrible but lotion seriously helps lol.
Mine haven't grown much maybe a cup size and I'm 37 weeks,
I got really bad stretch marks on my boobs with my first pregnancy and even worse on my belly. The good news though, you can hardly see them after. I didn't use coco butter or anything.
I'm almost 14 weeks and I've noticed I've been getting some stretch marks on my boobs as well. Hopefully it doesn't get worse lol I will probly get them on my belly as well but I got awhile to wait.
I wouldn't even mind if my.boobs would have grown alot but they barely even grown a cupsize and there coverd in stretchmarks but don't have them anywhere else.. I'm 32 weeks so I guess I still have time to get them lol
-.- mine started at my boobs but now there on my stomach but not to bad
