Is it normal to be nervous about getting married?

Tomorrow I get to see my Fiance after 7 weeks of being apart. I'm getting the ring in the next month and our engagement is going public. But I had this moment when I thought "What if I'm going to make a horrible wife?" He will be wonderful to me, but what if I can't make him as happy? Is it normal to have these fears? Or is my gut trying to tell me something?
