I remember mine didn't "balloon" until later on in the pg. Your time may still come
Not sure if you plan to BF or not, but you will have zero complaints about small boobs if you do! It's crazy how BIG they can get. I didn't realize until after I weaned and was like "where'd they go?!?!"
I got firmer - not bigger.
This is good because normally I am gigantic.
Is this your first or second?
My boobs didn't get bigger with DD until part way through first tri, but this time around they're showing no signs of heading that direction.
