Try not hunting for those signs so much. I am being a hypocrite just telling you that.
I did this once. Try puting a smile on that doesn't look fake, like you know something she doesn't, or that you just have something funny on your mind. See if she notices or says anything. If she does, just pretend like you didn't know you were doing it.
