Married or not?

Angelica • She`s hear! Mommy life begins!
I was slightly taken aback when the Drs office asked if I was married when I called to set up my first appointment. I'm not married but still trying to figure out why it matters? Now I'm worried about telling work I'm pregnant for fear of judgement. Any one else feel this way? 
Btw we were trying to get pregnant for the last year we just didn't tell any one. I'm afraid people are going to think we got pregnant on accident. 😒 I think I worry to much
