Nervous about telling my family that I'm TTC.

I'm 23, married, and in college while my husband works. We aren't super rich, but we're in a good place. Much more financially stable than many people I know having kids right now. 
But. 
I'm afraid to tell my friends and family that my husband and I are trying to conceive. I'm worried they'll judge me or think I'm throwing my future away. To me, however, having kids IS my future. That's all I want in life, really. 
Has anyone else felt scared to tell people that you're TTC, or did you keep it private until you got your BFP?
