Don't try to think about what you missed, I did the same thing. I went to work after my test, and I started walking the shelves trying to find things I missed. I came up with about 10-15 questions that I was sure I missed. I ended up making a 125.
I felt good about my test right after I took it, but the more I thought about my questions, the more I found that I missed. Don't worry about it. I'm sure you did fine
