Elective Ultrasound

Megan
I'm debating on getting an elective ultrasound and wanted to get some feedback. 
I will be 12 weeks next week when I would have the ultrasound, but my doctor's office won't see me before my scheduled appointment the following week, when I am 13 weeks. I plan to tell my family the news next weekend at a family gathering, but wanted a little bit more peace of mind before telling everyone. I'd wait for another time, but everyone will guess if I'm not drinking, skiing/tubing/hot tubbing. 
Has anyone else done an elective ultrasound at 12 weeks?
