When Do Breasts Stop Growing?

Kate

I'm 21 weeks, and my breasts are out of control. Pre-pregnancy I was a 28H, now I'm a 30K. I think I'm still growing. Gone up 3 cup sizes and already grew out of one of the bras I got around week 10. Don't have money to buy a new bra every few weeks! When did growth stop for you guys? If you've been pregnant before, when did your breasts start to shrink? My neck and shoulders are killing me!
