Will my boobs get bigger??

I'm 36 weeks pregnant and in my first trimester I thought my boobs had filled out slightly (I never had to go up a cup size, but I definitely filled up the size that I always wore, which was slightly big on me). Now I feel like they went back to normal... ?? Will my boobs get larger again when I start breastfeeding? Some people say that their boobs get bigger after they have a baby and stay that way? That's what I was kind of hoping for... is it still possible that it will happen for me?
