Delivering at 37 weeks

I'm delivering at 37 weeks via c section and planned on pumping after. The thing is, I'm not lactating yet. I've read online that milk doesn't come in until 3 to 5 days after delivery. I know I can supplement with formula but I want to avoid that as much as possible. Is there anything I can do/eat/drink to get my milk to come on faster? I've never pumped or breastfed before so I'd like all the help I can get in the hospital as possible.
