When did you get excited about being pregnant ?

I'm currently 10 weeks with first baby ... and still not excited about being pregnant . Is this normal ? All I can think about is the changes to come and how am I going to do all of this ? Plus I'm sick daily .. still not showing (not complaining) and haven't told my family yet .. so I'm thinking that's maybe the underlining reason for my ambivalence. 
Seems like most moms were happy from the moment they tested positive .. yet I've felt numb . Just wandering when this feeling passes ..... ??
