Announcement Question???

Jessica

Hi everyone!! FTM here, I am only ten weeks at the moment but my first trimester is up shortly before my cousins wife is slated to give birth to their first child. In an effort to not steal her thunder I have chosen not to tell that side of the family until after she gives birth. She is due the 17th of November and I really wanted to announce on Thanksgiving but I'm wondering if that is to soon after or if I should wait another few weeks??
