Planning to Tell Everyone

So we wanted to wait until the end of the first trimester to tell everyone just to make sure we were as safe as possible from miscarriage.  We figured this would work perfectly for us because I have a conference in DC planned for the week of January 24th (which would be right at 13 weeks).  We planned on having Amy fly down at the end of the conference and tell both sets of parents and then spread the news from there.  The only issue is that Amy's family has a huge family gathering scheduled for Martin Luther King Jr Weekend (January 15th) and we were worried that they would all know.  You see, Amy is somehow wired to be magnetically attracted to hot tubs, so with her not going in we thought for sure that would be a huge red flag.  But, we planned on getting around this by telling everyone we were trying and we didn't want to risk it.  Problem solved.  We also wanted a special way to tell the people closest to us, so we got some cool picture frames that said "grandkids" (or something like that) and we planned on putting an ultrasound in each one for our parents and grandparents.  The plan was in motion and all we had to do was wait.
