Simple advice - you are getting married. You will be together (God willing) for the rest of your long, happy lives. Things like this will happen - period on wedding day, flu on an anniversary, who knows what. Just remember a favorite quote of mine - "Life is what gets in the way of plans." Open up and be honest with your future husband. Let him know that you've waited this long and you want it to be perfect with him. Let him know what you wish it hadn't happened this way and you'd love to consumate your marriage on the night of you wedding, but you wouldn't feel comfortable, and as soon as your period ends you will let him know so you can have that special night. At the least you can dress up again that night in your wedding dress and let him take it off of you like you wanted him to on your wedding night. It's let's you remember your day, and you get to wear your wedding gown twice (a rarity). I'm sure any man that has the maturity and respect for you to wait until your wedding day will also extend it so you can both enjoy it.
Good luck and God's blessing's on your wedding and marriage.
PS - lesson to learn from this: if you are going to plan, you need to REALLY plan. Next time you want to set up a romantic vacation or something, make sure you schedule it at least a week away from when you are going to get your period. I know it's tough for a woman to plan like that since it's just a part of your life, but since being intimate with my wife is a very important thing to me, I've taken on the responsibilty of "period control". I track my wife's period so I can assit in ensuring plans are really planned accordingly for everything (period) <- pun intended
