Not wanting to announce pregnancy

Taylor
I have conflicted feelings about officially announcing my pregnancy to Facebook, extended friends, etc. because it was an unplanned pregnancy. I am happy and excited but being unwed,  not engaged or living with my boyfriend kinda makes me not want to announce. I'm not sure why I am so conflicted because although I am 23 almost 24 I have a great job (teacher) and my life together but something is making me not want to. Am I crazy? Am I the only one who thought this?
