looming labor? need experiences!

Julia
I'm 36 +4 and I spent Monday feverishly nesting. (Cleaning, organizing, laundry etc) yesterday I was extremely anxious for no reason at all. I found myself clenching my jaw and white knuckling my steering wheel which is very unlike me. I don't really have an appetite either. Saw the doctor and he said," good go into labor!" Which gave me the impression that these are signs. This morning I've had a few of what I consider Braxton hicks...
Has anyone ever experienced this before labor? I was induced with my first so I have no idea.
