I feel like such a child!!

Crystal • Married 10/12/14. Have an amazing son, born 11/27/15
So I'm telling my mother tonight that I'm pregnant. There is a four hour time difference so I have to do it over the phone. And I am freaking out! I feel like a little kid who did something wrong and I don't know why! I'm 29 turning 30 this year and was married in October. I'm a grown ass adult! I shouldn't be scared to tell my mom! Has anyone else felt this???
