Congrats on the positive! With both of my previous children, I was a 38D, then a 38DD. With my daughter, I gained a total of 12 pounds, and my breasts didn't get much bigger until the milk came in. With my son, I gained a total of 4 pounds and, again, my breasts didn't grow much until after the birth. This time, I started out as a 40DD...now I'm probably a 44DD, but I have only gained one pound so far. My breasts have grown a LOT this time, and I'm just 16 weeks now. Soooo...
