Frankly, nobody cares (or should care) about your stutter more than you do. What they care about however is the content. Sure, delivery might not be your strong suit but make sure that whatever you say is spot on. Do your hard work and know your stuff in and out. That will breed the confidence you need. I have faith in you, and remember that even if you do stutter a lot, all of us will still think the world of you. Good luck.
