Couvade syndrome aka sympathy pregnancy

My fiancé has a history of having prego symptoms along with the mama. He has almost every pregnancy symptom, but I have maybe one or two which can easily be because AF is on her way. AF is due on 11/21, and I'm hoping she doesn't make it, but I don't feel pregnant at all. Has anyone had a SO have symptoms before you took a test and you were actually pregnant? Please share any stories about sympathy pregnancy too.
