If your breast don't leak during pregnancy

If your breast don't leak during pregnancy does that mean you won't produce milk much? Will my milk come much later? Does your boob size matter? Cause I never see anyone with small boobs post pictures breastfeeding. Also, does the baby nursing hurt more than the pump?
