Is it normal for your boobs not to produce any milk while you’re pregnant?

I can’t really get a straight answer from Google, I was just wondering if nothing happens with your boobs during pregnancy does that mean you’ll not produce milk after you have the baby? Because I don’t have any symptoms at all and I know some women leak colostrum and have itchy boobs or sensitive nipples but that stuff doesn’t really happened to me.
