When do they hurt?

I heard that if you don't pump or breastfeed that your breasts start to hurt. I'm trying to dry up and they don't hurt yet. I haven't pumped or anything since the 4th. 
How long does it take to dry up? Are my breasts supposed to hurt? I'm sorry if those are dumb questions. I'm a first time mom so I've  never been through this.
