Telling Family.

Me and my partner have been together a year in November.
We have our own house and both work full time. In March of this year, I came off BC (implant) we decided to try for our first baby together. About a month later, we found out I was pregnant but sadly I had a misscarrige. 
2 weeks ago now we found out I'm pregnant again. I'm currently 6 weeks & 4 days.
My first midwife appointment is on 20th of September. 
My partners parents both live in Australia and Portugal so we will tell them over the phone but we want to wait till the first ultrasound to tell my parents. But we're not sure how to tell them. Has anyone got any unique ways of telling close family members?
