First baby announcement

Lizzie • My husband Kyle and I are expecting our first 🌈❤rainbow baby ❤🌈December '16!
I'm trying to find a way to announce on social media because all my friends and family live far away. I want to do something cute but the ones I like all either have animals or siblings in them and I have neither :( anyone's ideas would really help. I don't want to do the whole posting my pregnancy test though, and I'm not sure if I'm even going to be getting an ultra sound.
