Breastfeeding help

I need help with breast feeding. When I was in the hospital I was doing formula because I had a c section and was in pain. But now that we are home I don't think I gave it a fair try. Ideally I'd like to pump more because I will eventually be going back to work and would like to start building a supply up but I don't know where to start. I plan on contacting my local WIC office to speak with a lactation consultant but since it's a weekend and Monday is a holiday I'm in need of any advice you can give now. Do I breast feed my daughter and then pump right after? Do I pump both breasts? Please help I know I sound like an idiot but this is all new to me. By the way my daughter is 3 days old
