Hard time announcing pregnancy post MC

Jessica
I am currently 6 wks 1 day preggo after a loss in January. Our first ultrasound is 5/7, and assuming that goes well, we will need to figure out how/when to tell our families.
The last time, it was so fun. It was Christmas and we were taking a family photo, at the last second I yelled that we're having a baby and the pic captured everyone's responses. Then we gave my in laws "grandma " and "grandpa " mugs to open on Christmas morning with a note from the baby.
This time, I can't wrap my head around how to tell our families. When I imagine it, I picture myself almost being apologetic and saying "we've already been to the doctor this time and everything looks good" or "we're pregnant...for real this time..". 
This is not how I want it to be. This baby deserves just as much, if not more, excitement and enthusiasm as our first pregnancy. But I can't figure out a way around referencing our loss when announcing, especially since it was so recent.
Any thoughts or advice on this?
