mom told everyone.

Just need to vent. 
So we told my parents this weekend (cause they live far away) and my mother told me that she "knew" a month ago and proceeded to tell everyone she knows that she is going to be a grandma. 
So now that she "knows" she says she's gonna have a hard time lying to people so I can announce in a few weeks. I'm so irritated. We haven't been able to tell my husbands family yet because they live far as well. 
I just want to be able to announce when I want to but I know she's going to tell a bunch of people again.
