Pumping and breast feeding advice

First time mom. I just got accepted into my nursing program and it’s set for February 5th. Baby is due January 20th (Dr thinks he’ll be here sooner). I so badly wanted to beast feed and I do not want to do formula. How do you do it? How do I get my supply up as fast as possible to bag my milk while I’m at school? What’s a good feeding schedule and pumping schedule? I will only be in school m-th 8-12 with clinical on Saturdays 6-12. He will still be so little 😭
