Has anyone had issues breastfeeding with previous children?

This is my third and with both of my others I was unable to breastfeed. With both of my others I tried both pumping and at the boob for well over a month. My supply never came in. I've never dealt with my breasts hurting or being engorged or even leaking. Even during pregnancy I had no change. I'm worried that it will be the same with this one. I'm 35 weeks and haven't had any change in size, or tenderness, or any leaking of colostrum.
