Very interesting thought. I can tell you from personal experiences through nursing 5 babies, some early some term. Let's see, my best pregnancy that I carried term and went into labor naturally I had so much milk and Bella was the fattest little thing. My oldest was also term, but I really struggled producing enough milk, and I finally supplemented at about 6 weeks because he wasn't gaining any weight, and I was young, in college, and just didn't have the reserves physically to get my body in gear. With my three pounder, I pumped the first few days almost non-stop. I was at a VERY non breastfeeding hospital and they were going to give him formula until I produced milk (not colostrum). I was so stressed and sick, I had more blood in the vials than anything else, it was just aweful. A sympathetic nurse let me put him to breast, and he and I got the start we both needed. The doctor still refused to let me feed him after they found out about this incident and made me go back to pumping, but I was allowed to put him to breast for two minutes every 5 hours and then I would hand express after that as my milk would let down.
I just cannot imagine not getting to *nurse* my first, and how hard it would have been. I wish you the best of luck. Just remember to give your body everything it needs: rest, hydration, good nutrients, lowest stress possible, etc. to give you the best chance.
