We've been planning a wedding for September since last year. The STDC have already gone out last month. But last week, I just found out I'm pregnant. So we are thinking of changing the wedding date from September to July so that ill only be 4 months along instead of 6 months. That means the invitation should go out now. Do I need to say anything that the wedding date has been changed? If yes, what should I say? Do in need to announce that it's because I'm pregnant?
