Question for Ladies with big (before pregnancy)...I'm really worried!?

I have DDD's now, and I am 10 weeks pregnant. I am also really scared that they are going to get too big. I've noticed them getting bigger already, but I dont see them getting TOO BIG. You should be okay. I mean, you'll be able to nurse and everything. Then whenever you are done nursing, you can plan a reduction, that it what I am going to do.
