wedding advice please!

I'm Soooo nervous for my wedding day (it's in august). Like I'm so nervous to actually marry this guy/father of my child/high school sweet heart. We live together, have a baby, and plan to spend the rest of our lives together but now that we actually decided to tie the knot, I'm here thinking like is this right for me, and basically second guessing everything. I'm obviously. Not scared of commitment since I'm been with him 3+ years. My sister says it's my daddy issues coming up, but I just need a pep talk. Were you this nervous before your wedding?
