Marriage and baby

I have been with my bf for over 10 years now, we are happy and sometimes we do talk about marriage but neither one of us are in a rush, were committed to each other already. So now that I'm pregnant everyone at my job (we work at the same place) keep asking me if we are getting married and when is my bf gonna make an honest woman out of me which I hate when they ask me that. I mean I love my work family and I kno they are not asking to make me feel bad.  Has this happened to anyone else? What do you say to people?
