Christmas announcement at 8 weeks?

Rachel

I just found out I'm pregnant so I will be 8 weeks at Christmas. Will that be too early to announce? I think ideally I would like to announce at 12 weeks, but family is going to notice something is up if they don't see me have wine during the holiday.. I'm also wondering if I will have had an ultrasound and heard the heartbeat already before Christmas? This is my first pregnancy and I'm so excited, but I also just don't know what to expect.
