No Milk Yet - Late Preterm Baby

I gave birth to my 2nd baby yesterday. He was 37 weeks and 2 days when he popped out. I'm worried because no milk is coming out yet and I was really looking forward to breastfeeding this time. Is this normal? What can I do to make sure I can produce milk? This is really stressing me out. #LatePretermBaby #breastfeed
