Csection and breastfeeding

Raeleigh
Well it's been confirmed. I will be having a c section.. Between my low lying placenta and my daughter being breech. Is it true it's harder to breast feed after having one? Does it really take longer for your milk to come in? Would pumping the day or two before every few hours help to start my supply easier? 
I really want to last longer than a couple weeks with breast feeding so I want to make sure my supply starts good and continues well
