Pregnant and not married

So just a few short weeks ago I found out I was pregnant. I’m 5w1d. I’ve been with the same man 2 years, I love him very much. We already have a home together but I’m hoping for a proposal very soon. I have very religious family members who would straight croak if they found out I’m pregnant and not married. So I’m looking for someone in the same position who knows of the best time to get married and where to do it. I don’t want to spend so much money since I have a baby coming but at the same time I don’t want it to look so cheap that I’ve got something else going on since I’m not planning on announcing until we’re officially living under the same roof with the same last name
